Re: [SlimDevices: Unix] Announce: piCorePlayer 8.0.0 - Network Timing Protocol
Yes, it would be. It is something you probably only notice when there is another clock next to it, or maybe if you use a player as your alarm clock. Since the Pi hardly ever needs a reboot, it is a useful feature. scaleo home server 2105 & picoreplayer 8.1.0 | logitech media server 8.3.0 | server power control 20120716.103808 | transporter & duet & touch & boom & radio | rotel rc-995 & rmb-100 | nubert nuvero 140 mvordeme's Profile: http://forums.slimdevices.com/member.php?userid=22892 View this thread: http://forums.slimdevices.com/showthread.php?t=115268 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix

1000 sockets in two months would have been more than 15 sockets per day, but right now, everything is quiet. The LMS has 39 open file handles in total, of which 15 are sockets. That number has increased by one since I am watching it (which was before I started logging). scaleo home server 2105 & picoreplayer 6.1.0 | logitech media server 8.2.0 | server power control 20120716.103808 | transporter & duet & touch & boom & radio | rotel rc-995 & rmb-100 | nubert nuvero 140 mvordeme's Profile: http://forums.slimdevices.com/member.php?userid=22892 View this thread: http://forums.slimdevices.com/showthread.php?t=113321 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
Re: [SlimDevices: Unix] Memory Leak in Perl Engine on piCorePlayer?
Actually not. Originally, we used to shut down our WiFi overnight, but since our daughter has been on an unpredictable time schedule for a few months, we leave it up 24/7. I mean, now and then a player loses the connection, but I'd be surprised if it should happen frequently enough to explain this many open sockets. There is something else that might be related. When you pause a track on Tidal, the URL will only continue to work for some time. If you wait for too long and try to resume, there is some kind of error message, and the next track is played. But even that does not happen frequently enough. Is there any kind of logging I can activate which could help? scaleo home server 2105 & picoreplayer 6.1.0 | logitech media server 8.2.0 | server power control 20120716.103808 | transporter & duet & touch & boom & radio | rotel rc-995 & rmb-100 | nubert nuvero 140 mvordeme's Profile: http://forums.slimdevices.com/member.php?userid=22892 View this thread: http://forums.slimdevices.com/showthread.php?t=113321 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix

Re: [SlimDevices: Unix] Memory Leak in Perl Engine on piCorePlayer?
That is a fact which makes investigating the problem difficult. When there are 500 open file handles, it is difficult to keep track of what is happening. I understand from the code that with a memory configuration of high, the process should not use up more than 500 MB of memory. Is that correct? scaleo home server 2105 & picoreplayer 6.1.0 | logitech media server 8.2.0 | server power control 20120716.103808 | transporter & duet & touch & boom & radio | rotel rc-995 & rmb-100 | nubert nuvero 140 mvordeme's Profile: http://forums.slimdevices.com/member.php?userid=22892 View this thread: http://forums.slimdevices.com/showthread.php?t=113321 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
Re: [SlimDevices: Unix] Memory Leak in Perl Engine on piCorePlayer?
I am not sure about all the debugging stuff, but it appears to me that it is not a matter of configuring things but of changing the code. I have tried to increase the amount of logging for a few items but didn't learn much. Where is all the code? The directory containing the slimserver.pl only contains 9 pl files in total, and only gdresize.pl uses File::Temp. Code: tc@piCoreServer:/tmp/tcloop/slimserver/usr/local/slimserver$ find . -name "*.pl" -print ./CPAN/AnyEvent/Util/idna.pl ./CPAN/AnyEvent/Util/uts46data.pl ./CPAN/AnyEvent/constants.pl ./CPAN/XML/SAX/placeholder.pl ./cleanup.pl ./gdresize.pl ./gdresized.pl ./scanner.pl ./slimserver.pl But I used the opportunity to update the LMS and watch a fresh system playing an album from Tidal. I now understood why just counting the number of open file handles does not help with understanding what is happening. Every track creates and destroys two sockets and two pipes, and there are other activities adding to the noise, like the caching of album art. But when it comes to temporary files, the behaviour is rather straightforward. Every single track played leaves a temporary file behind with an open file handle in slimserver.pl. The files are rather uniform. They seem to contain mp4 metadata. I downloaded one of the mp4 tracks, too, and it looks nothing like those temporary files, although with binary data, this is hard to say. All temporary files start with binary data and end like this: Code: udtameta-hdlrmdirilst handlerilstr(meanorg.hydrogenaudio.replaygainreplaygain_originator_code data01101100i(meanorg.hydrogenaudio.replaygain!namereplaygain_track_gaindata-7.87 dBi(meanorg.hydrogenauIuuidDLBY-METADATA-00meta3hdlrdlbtdolby tags handlerxml http://www.dolby.com/ns/mobile/protected-1.0;> http://www.dolby.com/ns/mobile/tags-1.0; id="febbcb871e10fe78fcb42572d432c797" read-only="true"> LS1pbnB1dC1maWxlIDxhcmc+IC0tb3V0cHV0LWZpbGUgPGFyZz4gLS1hdWRpby1lbmNvZGVyIGFhYyAtLWF1ZGlvLWNici1yYXRlIDMyMCAtLWFhYy1tb2RlIGFhYyAtLWlucHV0LXNwZWVjaCBmYWxzZSAtLWF1ZGlvLW9ubHkgLS1yZXBsYXlnYWluIG9uIC0tYXVkaW8tcHJvcC1tZXRhIGxvdWRuZXNzIA== a8d5be608e4aca0266c159418d806a4e meta;hdlrdlbfdolby file metrics handlerqxml http://www.dolby.com/ns/mobile/protected-1.0;> http://www.dolby.com/ns/mobile/file-metrics-1.0; id="febbcb871e10fe78fcb42572d432c797"> Dolby Media Generator 3.8.3 2016-08-12T17:57:06 115124 Dolby Pulse Encoder 1.1.4 sbr: 4.0 / Aug 18 2011 AAC VBR 32 9765888 1c5f05da944468156c140c483176ed9d 44100 2 None 1600 0f2340c558a9c8d72d0ce1fadcd2ff28 mmeta;hdlrdlbkdolby audio kernel handler http://www.dolby.com/ns/mobile/protected-1.0;> http://www.dolby.com/ns/mobile/audio-kernel-1.0; id="febbcb871e10fe78fcb42572d432c797"> 3c207014a46f955c7c617a330a9d1029 3meta7hdlrdlbmdolby metadata handlerxml http://www.dolby.com/ns/mobile/protected-1.0;> http://www.dolby.com/ns/mobile/metadata-1.0; id="febbcb871e10fe78fcb42572d432c797"> 36bbff96c50793db343f56cc653f0adb )emdat The only time I saw one of the files being removed was when my playlist contained only one track and I skipped forward, playing the same song again.

Re: [SlimDevices: Unix] Memory Leak in Perl Engine on piCorePlayer?

Re: [SlimDevices: Unix] Memory Leak in Perl Engine on piCorePlayer?
Meanwhile, the LMS is using almost 800 M of memory. The process is
holding a total 696 of open file handles, of which 20 are sockets, 12
are files in /mnt/mmcblk0p2/tce/slimserver/Cache/ and 656 are files in
/tmp/. All these files do actually exist, and all existing temp files
seem to be associated with an open file handle.

Re: [SlimDevices: Unix] Memory Leak in Perl Engine on piCorePlayer?
Seems that I need to get my head around that funny Perl syntax after all. In the LMS settings, I can choose between normal, high and maximum database size.

Re: [SlimDevices: Unix] Memory Leak in Perl Engine on piCorePlayer?
I believe that if there really is an issue with file handles on my Pi, it is not the same that Simone has reported. My open file handles are back down to 459 and memory usage is up to 562 M. Since it looks like for every transcoded stream, a temp file is left over, but the number of file handles is not growing, I'll match the file handles against the temp files to get a better idea of what is happening.

Re: [SlimDevices: Unix] Memory Leak in Perl Engine on piCorePlayer?
I am not entirely sure what happened just now. The track I was playing was cut short by maybe half a minute and the next track started. The number of file handles went up by another 4 and after some time went down by 1. Also at the moment, the contents of /proc/32307/fd and the output of lsof don't tie up. There is a difference of 1. I just played the same track again, but this time, nothing out of the ordinary happened. scaleo home server 2105 & picoreplayer 6.1.0 | logitech media server 8.2.0 | server power control 20120716.103808 | transporter & duet & touch & boom & radio | rotel rc-995 & rmb-100 | nubert nuvero 140 mvordeme's Profile: http://forums.slimdevices.com/member.php?userid=22892 View this thread: http://forums.slimdevices.com/showthread.php?t=113321 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
Re: [SlimDevices: Unix] Memory Leak in Perl Engine on piCorePlayer?
On my Pi, the number of file handles goes up by 4 when starting playback and immediately drops again when playback stops. This appears to be good news at first sight, but nevertheless, the LMS process has piled up the impressive number of 459 open file handles in the last 21 days: Code: tc@piCoreServer:~$ sudo ls -l /proc/32307/fd | wc -l 459 The majority of these file handles point to temp files most of which are less than 100 k in size: Code: tc@piCoreServer:~$ ls /tmp 03cIFl7jwe 4rgI1aC5vc 9WJ4VtXcBL Gd9RHv3V1l NNPPF9ceUe Sl3yuXOz36 WuykGpS0xb bootlog.txtgKm8BgSzot mEQGU5SvOW rJkQlGJI8J wURF2K4f4K 0EmYhzJcmB 4tPPr4daxA 9kOwuZh3DW GmabeY5h3Q NTlU4uMxZo SsEtswHHAn WvCIsttz5m bzMqfrLxAV guEXqhnCGq mEp9BbzIyb rukbirJ2Vm wVhM2nDcQZ 0MgKy2CQgv 59OZNn7TZC 9ncQsIcC0T GvYFsnRz12 NZbdlVfobT Ssa2ci4XIw X6zZ6QDze7 c40jEOE2px hC1zbMSwlZ mLpFKaW1yL s4ESx3Ymud wWXbsZiJ20 0OdWqmUZXu 5EoPV3jX4t 9tzReGrzMm Hg1rwaMJQU Nb5kHNTXVK Sw1eZQg04O X94BfSP5gY c5kBHVyR90 hDFoTS1pt6 mcXUl3DsXH s4bQXZPW1N wXr80U6zsv 0VW1ORXGi8 5qtZGav2wm 9yDdWrfNFh HhKv5L1ozW NruzzJs1Um T0bBX5nUIx XCechksfUu cGaSipwMqP hSqo7SFjnL mqRSCx1FIO s82mYev8qQ wfqSFmkCa1 0iNoW2Ico0 5yi4EhKHHS A1tbR1pg34 HrjcbeYad8 Nx1pQGNdGk TBm6dOTIVO XUWUuZNkeL cICQETUXgO hWNDmZBFYx mu37x9zwHD sXJC56fXBc wiVr3HQwPk 0qKNEliEkl 604D2xW2Tt AaEYtvzAMB I0e7fkV9G6 O1VvyykKyv TGqW8Fs3OL XYU2njU0e6 cJEPfJnxFE hXwNydIFSS mzjDdGcRJq se46Pf42uA wk6oxnHMKn 0qkNkqI35F 6Qy9fMg2Wt AnKjz3mGy7 I5w5mUr4hw O5s04ZhuvZ TJ6RyApBlL Xbz31gOGIm cPzStqDQB0 hZjRd9lF00 n9YIrXeYHw sexeF2VROx wmbL4CgCXb 0unQjsdhxT 6WGXas0JgF B4TYWqilnd IDXJgiVJru OHpas4VD1J TOKksgRTmD Xc2vhUjjtq d3MNPBgpyP i3HwB8XJbA nDNobIBN6U sjDEsb8NSk wtlFddVnSf 1BVOZ2XO58 6lpc5Hz72e BILAwoAQbV IEGu7ZTHcx OLYrBtXlhm TTFITP0uvW XgGRJL9V1d d8buGmkIb5 iFWF8Ir4LQ nEye6aNZOU slimupdate/x13y3rNG7X 1CYPNL0GEs 6t7NbOMLiX BMDe4xvaVY IFecwjVZY5 Opo6TN3ru2 TkciUsvxFT XhuxXEX9DA dAWhKbIZ6z iJECPb3BTR nOtq4bk4Qh tELx8hMxrY x1zuzXUY2r 1CcvD9Vpbe 728rEKvRdx BYU8sN2gql IncXP37qXU P8C7rfNVlB TrqyHlAjDw Y9xRrqrDmI dCg2gXtpFQ iMLfib0C6P nbWRfHPoLK tRsPc4VdpT xB0IEgJfWR 1ZdVNpxEu7 7ACuIcyWP4 Bm4cXyA9bR J8am7gmDWf PQJ952a5q3 TuPUuLqapg YAtTtPXVkP dEIUtc7xxw ibPwSyx1K9 newdep.lst tbqL2ZYEXL xQLtqB6sbI 1fgdvPmnPZ 7Ew8nXotOR C68HQ4pbMd JFQ0d7rW6d PuM3rncSUe Tx6gd5AP7T YHuLaKQFi4 dLDfu8zfTw ilrsdprSUK nnbwLlRdME tce/ xRhfBKPNCx 1u0GHEQlQF 7GjOSv0tJO CpXr0PDULX JNdNFhsdXQ Q0YZtnyi9g U40bI0bgVI YSky3P8lHb dUxnq7qLUV imVlF508C0 nsC9mU2Z5T tcloop/xXkR2lIbYb 1yzJMX1dVk 7IAD7vYZwS Crr4Gv0bnD JPocnZeLJh Q97QZVUPHQ UFzbJURWJF YtQah9muru dbJk6RXBV2 immrxdWS9t o6E0LBA07F tmp.18jhiN xdx5D2lUAN 2HvwYk8MCS 7LbsrebwUg CtwXSukPiM JRs60MDOCL QOnb4i0ybg UNlImZPzrj Z96bAqmu7Q dg8AR3wXax ioow0K9ArG oDxX0roKmb txlHsN7Ijm xtMRobN8ZJ 2IApNBY1rq 7PIGNDgs66 D2uONQqI2k JYMzKBOFSM QTFc97PBBz UNqy2QUrnY ZHmfPq3ITY diOtzoNgJq isfSzmLrsz oIUhnZISSg tzxEDKuYOV xwAC0YWWr2 2lCmLwhhGv 7XKgKqCN2Z DY5QcaTz3J JnWccflg20 QX1iu33p5W UV8Dzkx8uc ZkEdWmhrc9 drGnCSBfBF ivnGZEP7vN oKSRjJA6lf u4JRuoOqI5 y6E4lbOjSE 2oes0nmgVo 7aDVmWnkwu DaPdB5GQM1 KJEAgBLkf0 QY1dJvGXwn UYqCoex4kG ZqBCgbHQ2p dropdown.cfg j8a8PPWvIk oSn9W4XjQA u6FBVMX2C1 y8qvpiMYND 2xcEfyp1UU 7bngchDriJ DkbfceTQ53 KRrBENMk9r Qfj1r76VGo UlJtjVsZce aAMbKfWFTo dydAPGv4Eh jDQaSysY9E oY200lYF9W u8Srsfdus6 yOwD1uPuhw 2zHo8AiIxo 7nIYfS249w DyuMagCTKO KhqHd5Imgy Qw8HVLPpBz UqLr4FTo6Y aGWnkQ8rRO e8Jj1hBYTg jrMvLCp6Y2 obD9xsa12h uEu4LwesSC yvejTHwJwv 30qVkfd0E0 7o0j1wo3EH E2TmgSf2yj KopDpxPt26 QwYuUAcMkt UrQdjwuHh9 aICyozsrVW eBYXtBpFPX jweUwdH9vl oguOUERzTo uZylAdOAsy zF8nHZGfdB 3FWr84IAx5 7r4nKLNbTQ E7xMHcGN0Q Kvh3rpbiHJ R5nbmn9QkS UvTqndB2gz aJk8YEA6xo eDwJDhTjWB k0LklNxGhi orhHMGKcRn udDXmQlJQg zkbUlGLixc 3R5hP9Elsv 82PD3FRdpU EAxn3QNhDo L1Xbiu6N55 RBWQ0Nwyyr UzpMA1Zkso aJtJaXx4wr eHzILmDRip

Just for your encouragement, since you seem pretty well on your way
without interference from my side: It seems that I can observe the leak
as well with standard transcoding settings, only it is so subtle that I
will probably upgrade my LMS before the Pi runs out of memory. My LMS is
up since about 20 days, and it currently has the following memory
footprint. So far, I have never seen it shrink.

If I knew Perl, I would even had looked at the code, but as it seems, the architecture of the code is more of an obstacle than the missing Perl knowledge (which is probably true for 99% of all software with more than 100 lines of code). There are other minor problems which I just can't put my finger on, and so I didn't even bother to report them. mherger wrote: > Would be great to see it tested!I'll try and upgrade my pCP, too.

Re: [SlimDevices: Unix] Memory Leak in Perl Engine on piCorePlayer?
One thing I found out just now: Whenever I skip the currently playing track, the connection is closed properly. The new connection is using a different port, so I don't think it is the old connection reused. Only when a track is played to the end does the connection hang around. I could have a look whether this happens at the end of a play list, too, or just when a new track starts playing. Garbage collection is dangerous because it is only triggered by memory usage. If there is still a lot of free memory left when connections become an issue, GC does not help. scaleo home server 2105 & picoreplayer 6.1.0 | logitech media server 8.0.1 | server power control 20120716.103808 | transporter & duet & touch & boom & radio | rotel rc-995 & rmb-100 | nubert nuvero 140 mvordeme's Profile: http://forums.slimdevices.com/member.php?userid=22892 View this thread: http://forums.slimdevices.com/showthread.php?t=113321 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix

I re-wired mains and network to the pi and, while I was at it, updated the LMS to Logitech Media Server Version: 8.0.1 - 1607087403 @ Fri Dec 4 14:26:56 CET 2020.

The Controller is still counting down the remaining time when the next track suddenly starts playing.

Re: [SlimDevices: Unix] Memory Leak in Perl Engine on piCorePlayer?
The same thing again today. The moment Tidal gets stuck, the pCP web interface does not load properly any more. And I noticed another thing: I configured the Transporter to power down the audio section when off. It was sitting there, clicking about once per minute. It seems that the entire server is out of connections.

Re: [SlimDevices: Unix] Memory Leak in Perl Engine on piCorePlayer?
Tidal got stuck again, today, and I tried a few more things. - On the Receiver, the MPEG-4 podcast did not play, either. It showed the same behaviour as tracks from Tidal, i.e. re-buffering and now and then playing a few seconds. - On squeezelite, Tidal tracks would still play, but they had some trouble taking off. The clock would start counting, but no music would play. After a few seconds, the music would follow, get stuck again, and start over. After one or two attempts and the occasional stuttering, the entire track less the first few seconds would play without any problem. It was the same for all tracks I tried. - On squeezelite, the MPEG-4 podcast played without any problems whatsoever. - Today, the piCorePlayer web interface was not working properly, either. The CPU temperature display for example would run into a "connection reset" error more often than not. I just restarted the LMS (took a few retries to load the LMS page), and the pCP web interface is back. Memory consumption of the LMS was at more than 210 MB and is back to 103 MB, now. Tidal tracks are playing properly again on the Receiver and on squeezelite. scaleo home server 2105 & picoreplayer 6.1.0 | logitech media server 8.0.0 | server power control 20120716.103808 | transporter & duet & touch & boom & radio | rotel rc-995 & rmb-100 | nubert nuvero 140 mvordeme's Profile: http://forums.slimdevices.com/member.php?userid=22892 View this thread: http://forums.slimdevices.com/showthread.php?t=113321 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix

Re: [SlimDevices: Unix] Memory Leak in Perl Engine on piCorePlayer?
I have not updated for a week, now, because I didn't want to introduce new uncertainties. The version is Logitech Media Server Version: 8.0.1 - 1606059084 @ Sun Nov 22 16:49:21 CET 2020. It is buffering. The Controller will show rebuffering ... and only now and then a short snippet will play.

Re: [SlimDevices: Unix] Memory Leak in Perl Engine on piCorePlayer?
A few results. When Tidal streaming got stuck again, today, I checked a few things. - The faad and flac processes had the same memory footprint as usual. - The LMS would still spawn new faad and flac processes when skipping tracks. - Local FLAC files (16 bit / 44.1 kHz) would play fine without down-sampling. - Local FLAC files (24 bit / 96 kHz) would play equally fine with down-sampling (to 48 kHz). - Deezer Smart Radio would play fine. - Connecting players to the LMS seemed a bit slow but worked. Unfortunately, squeezelite would not connect to the server as it had last night, so I didn't test direct streaming from Tidal, but I will, next time. In a vain hope that it would help squeezelite to connect, I restarted the LMS, and Tidal streaming was fixed. scaleo home server 2105 & picoreplayer 6.1.0 | logitech media server 8.0.0 | server power control 20120716.103808 | transporter & duet & touch & boom & radio | rotel rc-995 & rmb-100 | nubert nuvero 140 mvordeme's Profile: http://forums.slimdevices.com/member.php?userid=22892 View this thread: http://forums.slimdevices.com/showthread.php?t=113321 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
Re: [SlimDevices: Unix] Memory Leak in Perl Engine on piCorePlayer?
Currently, my FLAC library is on the other server, but I'll copy a few albums and test. Right now, I only have a Touch which used to be able to play Tidal natively. There have been no problems with that, as far as I know. "Seeking" within a track didn't work any more, last time I checked, but was fixed when connected to the Pi. I can install a software player on a PC and test. When the problem first occurred on the Receiver, I gave up on Tidal and played web radio, instead. There were no problems with that. Back then, I still suspected network problems like you do, so I started rummaging through my router's logs instead of testing the LMS, which is why I don't know much about other music sources. scaleo home server 2105 & picoreplayer 6.1.0 | logitech media server 8.0.0 | server power control 20120716.103808 | transporter & duet & touch & boom & radio | rotel rc-995 & rmb-100 | nubert nuvero 140 mvordeme's Profile: http://forums.slimdevices.com/member.php?userid=22892 View this thread: http://forums.slimdevices.com/showthread.php?t=113321 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
Re: [SlimDevices: Unix] Memory Leak in Perl Engine on piCorePlayer?
What I don't understand about the memory: The file system looks like
there are 2.6 G of virtual file system in memory, which is not possible,
and which would not leave 1.9 G of memory for the processes, so in some
way, the numbers need interpretation. I wrote "out of memory" because
that is my interpretation. I should have added a "?".
So far, there are no music files on the server, so the library consists
of my Tidal favourites only. I don't do much with it, just go to -Tidal
> My Favourites > Artist- on the Controller, pick an artist and album
and play. I would expect the process size to increase at these points in
time when it caches the album art, but it actually grows all the time
while playing.
The server starts new faad and flac processes for every track. For a few
seconds, they have an increased CPU usage, and they die a few seconds
before the track ends, so there is a buffer somewhere. I actually did
not check whether the server still spawns new processes once the players
get stuck.
So far, I have not synchronized any players.
It actually took me some time to notice that the problem is on the
server because I am mainly listening with my Receiver which has its own
set of problems. The server is connected to the router over 100 MBit/s
Ethernet, but all players use WiFi. In case of the Receiver, there is
even a WiFi repeater involved. In order to minimize my problems with the
Receiver, I have moved the WiFi Repeater very close to the Receiver. It
shows a signal strength of more than 90 % most of the time. The WiFi
router displays connection speeds of > 200 MBit/s between router and
repeater and > 50 MBit/s between repeater and Receiver. I can play an
entire 24 bit 96 kHz FLAC album over that connection without any problem
when the Receiver is in a good mood.
When the problem occurred for the first time, I then moved to the Boom
in the kitchen, and it showed the same behaviour. There is no repeater
in the Boom's network path, and it has never shown any problems during
playback, so far. When the problem persisted, I updated the LMS, and the
problem was gone, but the next night it was back. This time, I just
restarted the LMS and everything was fine again. That's when I started
to monitor the processes on the server.
I don't think that it is a network problem because restarting the LMS
consistently helps every time. If you have an idea how I could debug the
network, I can of course try. I already gave the piCore real-time
priority on the router to make the inbound stream more reliable.
While I am writing, I had to restart the LMS again. This time, it had
only reached a size of 154 M, and the processes for transcoding were
still looking good memory-wise. The CPU load does drop when the player
re-buffers, but the problem appears to be on the server.

You can see that the shared and cached memory sizes drop when the LMS is
restarted. Both of these sizes do also grow constantly while the LMS is
playing. I'd think that it is okay as long as there is enough free
memory to go around, but the fact that they drop instantly when the LMS
is restarted could hint at some kind of resource
[SlimDevices: Unix] Memory Leak in Perl Engine on piCorePlayer?
For a few days, now, I have been running a piCorePlayer 6.1.0 with LMS
on a Pi 4 B with 2G of memory. I mainly use the Pi to transcode AAC
streams from Tidal. There are no additional plug-ins installed.
I observe the following behaviour: After the LMS is started, it will run
without complaints for about a day, and then the connected players will
suddenly start to re-buffer all the time and eventually stop playing
altogether.
I have been looking at CPU and memory consumption on the Pi (I don't
quite understand how the in-memory file system fits into it) and noticed
that the main Perl process seems to be hogging memory. When a certain
limit is exceeded, the transcoding processes suddenly will not have as
much memory as they used to, and the re-buffering will start. I have
monitored the system with top for a day and copied the output.

The Perl process is constantly growing from 100m to about 200m. The faad
and flac processes run with 5404 and 2780 k of memory consistently all
day until the re-buffering starts. I can't make anything of it since the
O/S still seems to have plenty of memory to spend on caching, but maybe
somebody else can.
