I'd > have loved to send you a link, but I didn't find a way to do so :-) I do remember very well the discussion. I have made a few additional tests and in fact the DESTROY happens as expected when the cache is set to 10 but it need to be created with 10, not modified later at runtime as I was doing before. Still, that does not solve the issue of open handles. I guess we can tolerate a large number of files in temp, but we cant have them opened. According to what I have read, File:.Temp unlinks the file when it is closed, so I would need to do something different like having a temp file that I only unlink in DESTROY but is closed unless the header is needed ... crap, that means I cannot rely on File:Temp for the random path/name generation and I need to memorize the name and reopen/close it all the time. I was hoping that the cache of $tracks would be decorrelated from playlist length and that LMS would re-read the ones that went out of LRU cache.

Re: [SlimDevices: Unix] Memory Leak in Perl Engine on piCorePlayer?
No, AFAIK, 500 is the number of cached tracks. After that, they should be closed but I'm not sure that works as expected. I've reduced that to 10 and traced DESTROY it's very unclear to me when it happens, except when you terminate the slimserver process.

I'm working on getting the 256x64 grayscale solution working, it been far too long and I want it closed out. Working on the full scale 2 up VU I noticed the meter was none too responsive - I see the wobble you described :mad: I have a test bench that I used to record the data stream and the resultant math pushing those data through the test bench and the numbers from the current algo don't match the recorded If I feed the recorded calcs in the meters look good as expected Code: 61,68,66,66,113,100 SA L: 61 R: 68 dB L: 66 R: 66 XY x: 113 y: 100 XYd x: 30 y: 18 Retrieved line of length 22: 114,115,66,66,103,168 SA L: 114 R: 115 dB L: 66 R: 66 XY x: 103 y: 168 XYd x: 31 y: 17 Retrieved line of length 21: 369,370,66,66,85,180 SA L: 369 R: 370 dB L: 66 R: 66 XY x: 85 y: 180 XYd x: 35 y: 15 Retrieved line ... XYd are the numbers from the current algo. I don't remember changing this but something is definitely amiss. Last time I touched the code was to add damping on the needle - improved "pseudo" mechanical physics I'm digging through source control to see when this was modified and I'll flip it back or reverse engineer the math.

Re: [SlimDevices: Unix] WPA-EAP enterprise wifi on picore player
Last I checked, wpa_supplicant is built with the same compile options as debian. But I have no way to test enterprise stuff. I would run wpa_cli, and try to execute commands and see what it says.. it should give you more debugging info. Obviously you will need a keyboard/monitor or ethernet connection to the device while you test wifi. piCorePlayer a small player for the Raspberry Pi in RAM.

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.
