For about a week now, ive been chasing my tail. Ill have unraid detect an unclean shut down, and this of course kicks off a parity check. The server is acting as though someones holding down the power button to force a shut down, then rebooting. I have one disk thats in an errored state, ive left that not mounted until i can replace it. Really pulling my hair out with this one, latest occurence was feb 4 at approx 140am. It might be 3 hours between these events, it might be two days. 

Syslog.txt

this just happened again while i was logged in, and not a thing in the logs at the time. looks to be hardware related, power supply or motherboard. Ill mark this as solved as its not unraid related really

You should post the complete diagnostics, also check this.
