Diagnostics file attached.

 

Around 3 months ago, this server began to crash after being booted for about one hour. After a lot of rebooting and troubleshooting I was finally able to get it stable again by enabling "VFIO allow unsafe interrupts" on the VM Manger page. In the last few days, the symptoms have come back. 

 

Immediately before crashing it does not put anything into the syslog or any other log file indicating a crash. I kept looking for a stack trace or something, but could not find one. It is just as if someone pulled the power cord out of the server. 

 

This unraid server has been around for 6-7 years and has been mostly great. It suffered from that old Ryzen sleep state bug a few years ago. Around a year ago I added two GPUs into this system to passthrough to two windows VMs. The server worked great for several months following that change. I replaced the power supply in the server when I originally had this crashing problem a month or two ago.

 

If anyone has any guesses or insight to what could be happening, please feel free to weigh in. I'm officially stumped.

If there's nothing logged it's difficult to guess what the issue could be, one thing you can try is to boot the server in safe mode with all docker containers/VMs disabled, let it run as a basic NAS for a few days, if it still crashes it's likely a hardware problem, if it doesn't start turning on the other services one by one.

Jorge, thanks for the reply. Sadly booting in safe mode yields the same result. Booting typically but with VMs and Dockers disabled also yields the same result. 

 

Do you have any intuition on what kind of hardware issue it could be? I suspected the power supply, but it clearly wasn't that. Is this what bad RAM crashes look like?

 

Thanks for the help

Difficult to say, but if you have multiple sticks try using the server with just one, if the same try with a different one, that will basically rule out bad RAM.
