OMV started crashing after kernel updates(?)

My system started crashing suddenly a few days ago after some updates, I think it was kernet updates but i'm not sure. (I'm updating once a week if there's any updates via GUI).
I did backups via GUI feature of backup so I have few full backups.
Crashes happens after system up and wait for about 20-30 minutes so I can do a quick actions before it crash again and again.

Attached photo of crash, maybe logs will help but I can't get actually where the logs lays.

Zitat von tkaiser

At the bottom you see that Plex Media Server seems to be affected by 'corrupted page table'. If you get these messages with different processes I would run a round of memtest86 to check for memory corruption.

Can I run this test within OMV? or the bootable memtest would be best way to run it?

About the proccess of Plex you see there, Plex running on Docker so I turned off all images in Docker but the issue still presents with other messages.

Solved:
For some reason, in Plugins, Plex plugin was installed even when i uninstalled it because I installed one on Docker.
When uninstalled it, no more crashes.

Edit:
Still happens.
