I just saw this on boot up after a random system crash. The tower just became inaccessible vis web or SAMBA. I attached a monitor and after reboot I saw some strange errors after it got to the login prompt. I am currently in the middle of a parity rebuild (replacing a possible failing drive) so I don't want to re-power down just yet, but here is a snippet of the log and I'll attach the full diagnostic as well. Doing an intial search I saw some threads somewhat similar where new RAM seemed to fix the issue. I've had this system running perfect for years...I guess there is a chance the RAM has gone bad. I can run memtest after the parity rebuild finishes.

loop2 is the docker image, try deleting and recreating.

Ahh okay. The entire image...so all my dockers?

Yes, but you can easily add them back, see the link.

Yeah, should be easy enough. Thanks for letting me know what loop2 was!
