I have been have instability with my setup lately and I am not sure how to read the logs. I attached the diag zip collected after the forced restart and the syslog from when it locked up. Squid has already helped me identify a memory problem. I am hoping to verify if this looks like a symptom of the memory problem or 2nd problem.

For context I clicked Docker "Update All" button. Everything was going well until tried to stop the Plex docker. I think a parity check was also running at the time.

I would try reseating the cabling to the drives & HBA

Thanks again. Things I have done with my GA-7PESH2 board:

1) Flashed BMC from 1.43 --> 2.43
2) Disabled C states "C State limit == C0"

3) Re-seated 2 RAM sticks that gave errors

4) Re-seated SAS connectors.

Turns out my motherboards PWM fan control is dumb. It was running all fans so low that the CPU fans didn't even spin up. Turns out a pair of E5-2650V2 being passively cooled in a case with real bad air flow probably causes instability.

 

Thanks to this post  I discovered the fun little fan dance I need to do to get the fans to run at full speed.
