Machine Check Events hardware problem detected

Hello, and thanks in advance for any help/advice you can offer. I'll try to provide as much detail as I can here.

I was experiencing some weird playback issues with my Plex server, so I restarted the server. Upon a clean restart, I had a disk report that it was unmountable. After some digging, it seemed to be a filesystem issue and I ran through the xfs_repair instructions here. This didn't fix the issue, so I ended up having to remove the disk from the array and rebuilding it.

The server went through a data rebuild and completed successfully. After that, the disks all looked fine and the array appeared to be functioning correctly. I started extended SMART tests on my smaller drives, including the disk that had originally presented a problem, and went to bed. I also ran short SMART tests on the larger disks and those seem to all have completed successfully.

When I woke up, the server had gone through what seems to have been a hard reset and was running a parity check. Fix Common Problems reported an error:

Machine Check Events detected on your server

 

Your server has detected hardware errors. You should install mcelog via the NerdPack plugin, post your diagnostics and ask for assistance on the unRaid forums. The output of mcelog (if installed) has been logged

 

So I'm posting my diagnostics file here and asking for any help you guys can offer.

A quick skim through my syslog and it seems like these are concerning lines:

Dec 3 07:54:09 dunbar root: mcelog: ERROR: AMD Processor family 23: mcelog does not support this processor. Please use the edac_mce_amd module instead.

A few searches in this forum turned up bad memory issues, so I'll run memtests as soon as the current parity check finishes, but please let me know if there's anything else I should be looking out for.
