Stability issues 1.28.x on 64bit Linux

[homebrandcola]

Server Version#: 1.28.0.5999 / 1.28.1.6018
Player Version#: 8.7 (iOS) + Plex web running on Plex Server

I have had repeated crashes after updating to 1.28.0.5999, and then after downloading 1.28.1.6018 from the Plex website, they continued.

Rolled back to 1.27.1.5916 with a manual install with dpkg over the top of 1.28.1 and it is stable again.

Crash dumps were uploaded to Plex automatically I think, however I wasn’t able to manually retrieve the files before the service automatically restarted.

Logs:

1.27.1.5916 has been rock solid after rolling back.

Just back from 3 week holiday.
Noticed my Plex is no longer working. There have probably been several version updates since I use watchtower to update my docker images, so I don’t exactly know since what version it went wrong.
Only thing I’m seeing is lots of continuous errors like:

today at 21:51:36****** PLEX MEDIA SERVER CRASHED, CRASH REPORT WRITTEN: /config/Library/Application Support/Plex Media Server/Crash Reports/1.27.0.5897-3940636f2/PLEX MEDIA SERVER/edfeb1ca-0144-406b-d7779ab8-315d01a8.dmp

I see dmp being written, then it disappears. I have no other clue to what might be causing this.

Any clue to what may be causing this?

I have tried versions/tags 1.28.2, 1.28.1, 1.28.0, 1.27.1, 1.27.0, all causing the same crashes (corrupted library?)

Just did an update of my QNAP to latest firmware, which needed a restart.
After that Plex server was starting up and I could reclaim my server (after password change I had to do recently).
I guess the restart of the NAS would have done it. Still not clear from the logs though what the actual problem was.
