System was stable when first set up last summer, but at some point earlier this year I've been getting progressively worse system locks (originally happened once every few weeks, now it's almost a literal daily occurrence.)  Entire system stops responding (dockers crash, GUI becomes inaccessible remotely, and I can't even get into the server folder through another computer.)  Only recourse is to do a hard physical reset on the machine.  Ran a 24hr memtest with no errors reporting. 

 

No idea if it's at all related but I can also only successfully boot the computer if I go through the bios menu (log into it and just exit out without changing any settings.)  Trying to let it boot normally just leaves the system at a blank screen with no progress.

 

I'm hoping someone would be able to translate the error messages I'm seeing in the attached logs.  I've  tried searching some of the terms but haven't been able to get very far in determining what they actually mean.

 

Much TIA.

The syslog you attached is the same as that already included in the diagnostics. It contains no information about what happened before reboot. Setup syslog server so you can get syslogs after crash to post.

 

Your cache has corruption of the sort that might indicate memory issues, but you said memtest passed. Suspect some hardware problem is to blame though.

Unrelated, but your appdata, domains, system shares have files on the array. Docker/VM performance will be affected with these on the array, and array disks can't spindown since these files are always open.
