Hello all,

I happened to login to my unraid (v6.11.5) node today and saw a red notification stating "Errors have been found with your server".
Under the settings tab, I see the following message;

"Your server has detected hardware errors. You should install mcelog via the NerdPack plugin, post your diagnostics and ask for assistance on the Unraid forums. The output of mcelog (if installed) has been logged"

Syslog excerpt below; I'm also attaching the full log and diagnostics zip files.

Any help or suggestions would be greatly appreciated.

This looks like a CPU cache error, but the error was corrected by ECC, if it's a one time thing you can ignore, if it keeps happening I would try with a different CPU.
