PMS is intermittently crashing with a seg fault

Plex Media Server NAS & Devices
1

Hi Guys,

QNAP TS453Pro running the latest QTS firmware (issue was occuring prior to this latest firmware). I am seeing Plex dropout, and a SegFault in DMESG. I have Verbose logging enabled (because in previous forum posts people said it needs to be on), and have a snapshot of all logs at the exact moment it occurs (have stripped out anything older than 1hr before the segfault). I can’t see much in the logs that helps why it’s crashing. The crash seems to occur even if no players are active, and I see seg fault in the linux dmesg when it occurs.

Server Version#: 1.22.2, but also does it on 1.21.x
Player Version#: Many different

I do have the logs, though not sure if it’s safe to share them publically? There was a successful crash upload too which I have the URL for.

Any assistance? I have plex pass.

[86698.866414] Plex Media Serv[27212]: segfault at 0 ip 00000000019175bc sp 00007ffb01c3c2d0 error 4 in Plex Media Server[a2e000+f59000]

I can see a few uploaded crash reports. Would like to have the server logs for the time of the crash

If debug logging is already enabled, then please get the logs and i will check if they cover the time of one of these crashes

If not enabled, please enable it and restart the server and wait for next crash, Download the logs after the next crash and upload the zip here

and please run with the latest beta - see plex.tv/downloads

Hi @sa2000 , Thanks - I have a full copy of the logs for when it happened. I had also nuked all the logs shortly before capturing the crash in these logs, so there shouldn’t be too much excess noise in the logs. I’ve also created a text file with the exact date/time of the crash (Apr 20, 2021 08:38:01.168), I have zipped a copy of all the logs and put into a dropbox share (1.6mb), may I PM that to you? (or is it safe to share logs publically?)

Interestingly, yesterday I completely removed PMS, reinstalled to 1.22.2, imported my libraries - and it ran like a dream for 6 hours under heavy duress too without an issue. Until, i started a long standing WT Utils app (which looks for orphaned files, subtitle mananagement) … then PMS crashed within a minute. I’ve since stopped (and remove) WT Utils, but even so PMS is back to the same behaviour of crashing frequently (within an hour or two, even idle), so i don’t know if WT Utils “did something” to it.

Either way I will PM you the share link of the ZIP file … very much appreciate your help.
Cheers,
Davidson-NAS.

ps have updated to PlexMediaServer-1.22.3.4392 (which is new, via plex pass downloads option on download page). Doesn’t say BETA anywhere though. Issue persisted this morning after updating to 1.22.3.4392

Thanks

I have referred the logs and related crash to the development team.
It does not appear to be a wide-spread crash

Thanks Sa2000 … it appears to have completely resolved itself (touching wood and crossing my fingers whilst typing this). Unsure what changed.

For posterity though, if you do get a response from Developers, it would be great to know.

Cheers for the response /help.
