Machine check error event after server crash

[Walker843]

Hello,

 

My server crashed at about 16:35 yesterday, and when it came back up the fix common problem plugin reported I had a machine check error event. I would appreciate help in finding out what caused it as I assumed whatever it was is the same problem that caused the server to crash. I've attached my diagnostics, and I also have the syslog if that would be helpful.

 

The crash also caused a parity check, which is expected, and several of my docker containers became corrupted and had to be reinstalled. Still working through that part as the parity check continues for about another day yet.

 

Thank you for any help!

Top of my head, the mce is because of the microcode update being issued to the CPU and is probably no issue

Ok, sounds good! I'll go ahead and set Fix Common Problems to ignore. I also noticed it had an MCE that has come up in other forum threads a few times and the general consensus is that it too can be safely ignored:

 

mcelog: ERROR: AMD Processor family 23: mcelog does not support this processor.  Please use the edac_mce_amd module instead.

 

Thank you for taking a look, much appreciated!
