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?
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.

It was a good while back and I think it may be good to look again. I wonder whether the contents of the file somehow results in a scanning error. For scanning streamed audio, the audio header (to be scanned) is saved in a temporary file usually created using File::Temp->new() and it is possible to do have better control over the temp file. My initial idea would be to use TEMPLATE so that the name of the temp file has additional info such as code module, streamname, format etc. - the "lsof" can then be used to see if any commonality in the files being left open. It is also possible override auto deletion when the associated object is destroyed so contents can be examined The File::Temp also has its own debugging which can be enabled although not sure what it produces - but ultimately it is the module which is responsible for deleting the file. bpa's Profile: http://forums.slimdevices.com/member.php?userid=1806 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

Trying to find a pattern, but no success, so far. I thought that maybe the mechanism of releasing the files is working in general but leaving the odd file behind.

are files in /mnt/mmcblk0p2/tce/slimserver/Cache/ and 656 are files in

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.

Here is the code in charge of limits
Code:
sub init {
$cache = Slim::Utils::Cache->new;
my $maxPlaylistLengthCB = sub {
my ($pref, $max) = @_;
if ($prefs->get('dbhighmem')) {
$max ||= 2000;
$max = 2000 if $max < 2000;
}
else {
$max ||= 500;
$max = 500 if $max > 500;
$max = 100 if $max < 100;
}
my $cacheObj = tied %Cache;
if ($cacheObj->max_size != $max) {
$cacheObj->max_size($max);
}
};
$maxPlaylistLengthCB->(undef, $prefs->get('maxPlaylistLength'));
$prefs->setChange($maxPlaylistLengthCB, 'maxPlaylistLength');
}
So if you have set the "high memory usage" in LMS settings, it's 2000. I
did not remember that

Big News.
Starting LMS with LC_ALL=C instead of LC_ALL=en_US=UTF-8 solves the
bug.
My first reaction was "How the f a locale setting can cause a memory
leak of 12GB in an OS used by servers (Netflix included as an
example)??" Because this seems to be a bug of the OS and not of Perl
itself.

The process will fill all the RAM and then crash. The "long-term"
depends on the transcoding. In extreme cases it can take 2 hours to fill
12GB and then crash.

I'm gonna try the fix mentioned in the github issue you linked. If it
fail I'll setup a vm on my server and I'll send you credentials. (I'm
unable to send you MP, don't know why, do you have an e-mail addr?)

There have been user of LMS on FreeBSD system for a good while and transcoding is bound ot be used - yet I don't recall crash report. Could it be that the behaviour (i.e. don't shrink memory allocation from "high water" mark is normal for FreeBSD) is normal FreeBSD and that perhaps FreeBSD does shrink it back if resources get stretched. A bit like the 500 file handles issues just discussed. @Simonef Assuming this is not a LMS bug. What is the long term detrimental effect of large memory allocated to LMS - does system crash ?

Re: [SlimDevices: Unix] Memory Leak in Perl Engine on piCorePlayer?
I re-read the pipeline code and I can only think that BSD screws up
either with the reader/writer/source socket by not releasing buffer when
using localhost sockets or in that code
Code:
if ($writelen) {
main::DEBUGLOG && $log->debug("Wrote $writelen bytes to
pipeline writer");
if ($writelen != $pendingSize) {
${*$self}{'pipeline_pending_bytes'} =
substr($pendingBytes, $writelen);
${*$self}{'pipeline_pending_size'} =
$pendingSize - $writelen;
}
else {
${*$self}{'pipeline_pending_bytes'} = '';
${*$self}{'pipeline_pending_size'} = 0;
}
}
else {
${*$self}{'pipeline_pending_bytes'} = $pendingBytes;
${*$self}{'pipeline_pending_size'} = $pendingSize;
if ($! != EWOULDBLOCK) {
return undef; # reflect error to caller
}
last;
}
The 'pipeline_pending_bytes' are not released either when being shrunk
or re-assigned to the substr() of $pendingBytes. In any case,
unfortunately, it looks like an obscure BSD+Perl issue that will be
quasi-impossible to track w/o a full system and my FreeBSD VM is a real
pain to use on VirtualBox as some of the drivers does not work well.

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.

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

A lot of buffering is associated with a file handle. Perl will only garbage collect resources associated with a file handle when it is closed and no longer in use.

Thanks a lot for the encouragement.
It seems to be correlated proportionally to the type of transcoding you
want to do.
As an example:
With very small files and light transcoding (to MP3 for ex) It takes
hours to show a minimum RAM usage above the normal (where normal Is
~120-200MB)
With a more intensive transcoding, like an upsampling of a FLAC file, It
Is pretty noticeable in a few minutes that the RAM usage starts
growing.
I tried with an Extreme case like FLAC->RAW 32bit/384kHz->1 milion taps
FIR filter -> DSD128 and the RAM usage of the perl process starts to
grow like Crazy (1gb After 2 songs).
What Is curious is that also the CPU usage grows proportionally, and I
mean not the CPU usage of the external utilities used for transcoding
but of the slimserv.pl process; in the last case It was using 30% of one
core of a xeon e5-2697 V3, which Is A LOT.
I'd like to solve it because I'm pretty much the only unofficial
maintainer of the version for FreeBSD/FreeNAS/TrueNas, and for the
moment, I answered to those who contacted me about this bug to set up a
cronjob to restart LMS periodically so it doesn't eat all the RAM As
a temporary "fix"
With Debian 64bit this bug does not seem to happen at all.
I tried to proceed on the 'memory debug' route.
2 of those modules needed for the memory debug were not working,
(B::Size and B::LexInfo) they are not maintained (for something like 15
years). I managed to fix them, but still MemoryUsage.pm gives another
error, It tries to call the 'FILL' method in the B::PADNAME class in
B::C, which, in fact, does not seem to exist. (See here
https://perldoc.perl.org/B#B::PADNAME-Methods)
In the mean time I managed to update all the CPAN modules in
slimserver-vendor and correct the building script accordingly (some of
them were out of date by more than 10yrs), Tomorrow I'll make the pull
request.
@philippe_44 or @mherger at this point I'm pretty stucked. If One of you
Is willing to help and try to recreate the bug in a local VM I'll send
you instruction in PM (It pretty quick to recreate It). I usually Always
try to find the way out by myself, but my weak knowledge of perl is
limiting and I'm a bit lost After all these failed attempts.

P.S. while I was messing with the buildme.sh script I made some fix, updated some modules and added a command line argument to make the compile multithreaded. Once I solved this memory leak problem I will make a pull request on github so you can decide whether it's worth merging or not. philippe_44 wrote: > But then you are not playing HTTPS services, right?

You'll need to install Devel::NYTProf for your Perl. And then run with above parameter. Please note that running LMS this way can generate a ton of data which will take a while to analyze by the NTYProf tools. But Ok installed all the dependencies required. Had to fix some of them because very old. I expected to find the result in server.log but I was wrong. I'm sorry, I got that wrong... Devel::NYTProf is not used for the memory monitoring, but CPU. I believe I never got server.memory debugging working in recent years... From what I understand reading the module it requires the following: use B (); use B::Asmdata qw(@specialsv_name); use B::Size (); use B::LexInfo (); use Devel::Peek (); use Devel::Size (); use Devel::Symdump (); Data::TreeDumper If you get server.memory working, you should have a new web page /memoryusage.html which would give you some overview of the memory usage. -- Michael ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix

I would suspect that it has to do with database management. Possibly linked to online music integration.

If usually a process takes from 100 to 400MB of RAM and now It continues to grow until the whole 12GB are saturated then it's not entirely wrong to suppose that a memory leak Is happening.
