I also have noticed this since I enabled the new Sonic Analysis feature on my Synology DS718+. Plex has been running smoothly for a long time, but now crashes (seemingly randomly) but frequently. My own logic seems to think it’s related to Sonic Analysis as the logs are either vague or undecipherable - for instance:
****** PLEX MEDIA SERVER CRASHED, CRASH REPORT WRITTEN: /config/Library/Application Support/Plex Media Server/Crash Reports/1.24.4.5081-e362dc1ee/PLEX MEDIA SERVER/65c46396-4fbd-466c-a4458da6-d917eafa.dmp
I then try and open said file, but it is several MB in size and often contains incomprehensible text / characters.
FYI - I see the above note from my Docker container logs, running the https://hub.docker.com/r/linuxserver/plex image from LinuxServer.io.
In my efforts to understand what was happening, I stumbled across this post, which I tried but did not resolve the issue as I’ve experienced a couple of random Plex Server crashes since - again for context, I tried the following:
This did not really do anything for me, and rebuilding indexes did not seem to do anything (I essentially rescanned my music library after the above).
I don’t want to disable Sonic Analysis, but I may have to if this is the only way to stop my Plex Server from crashing (plus I hope it does actually fix it)…
EDIT: Updated with some info
Looking at my crash dumps (located in /config/Library/Application Support/Plex Media Server/Crash Reports), it looks like I had zero *.dmp files until PMS was updated to version 1.24.3.5033-757abe6b4 where I started to get random crashes in the PLEX MEDIA SERVER folder where several *.dmp files are now found. In all previous versions (starting at version 1.17.0.1841-d42cfa161 have no *.dmp files, so I’m guessing this is related to the introduction of the Sonic Analysis feature.
EDIT 2: Added logs as per this post:
