Mystery full system crashes - neomic - 2023-08-17
My system seems to keep crashing needing a full manual physical restart. I can't guarantee it's based on Jfin, but that's the most used program on the server, so it's my first place to check. Here is a log. You can see it stopped logged at 2:42 and didn't restart till 4am when I got home and reset the system.
Other software I'm using related to jfin:
qbittorrent
radarr
sonarr
jellyseerr
mergefs
I know a drive is having issues being read (poor thing is dying), but I confirmed that the last show that was watched tonight before crashing (Black Mirror) was not being stored on that drive. I'm not rulling out that mergefs is part of the issue, since I assume it tries to re-read all the drives more often than just jfin, but I don't think that drive is the direct cause. I THINK it's something to do with transcoding, but I also can't confirm. Please let me know whatever else may be needed, and I thank you for your time and help.

Check /var/log/messages for anything that could guide you to the root cause. But log doesn't indicate Jellyfin is the problem.

Is it that Cron job?
RE: Mystery full system crashes - TheDreadPirate - 2023-09-13
When searching for that cronjob I found these two things. One said that their turned off XMP (possible unstable RAM overclock) and one made changes to the cron job.
