Server Randomly Shutting Down

[lime111]

Hi, my server (6.9.2) is just turning itself off randomly, i'm really not sure how to troubleshoot why.   It's an old rig by now but has been rock solid for so long.  I had a spare power supply so i replaced that, so it's not the PSU causing the issues.   Any assistance is greatly appreciated. 

 

PS yes noted disk 1 has read errors ill replace it once i know i can rely on the rig to stay up for long enough to write.  all diagnostics files copied below.

 

Thanks in advance.

Check fans and CPU temp, if the server shuts down vs crashing it's usually a hardware problem and not something easy to diag remotely, one thing you might want to confirm is that no shutdown command is being sent to Unraid, by for example a faulty power button, you can do that by enabling the syslog server and checking it or posting after the next shutdown.

 

P.S. next time please post the diagnostics.zip, not all the files inside it.

Thank you @JorgeB

 

I removed the CPU heatsink, fully cleaned and reseated it with good quality paste and it seems to be working again.  So appeared to be CPU overheating which makes sense.  thanks again.
