I'm getting a "Machine Check Events detected on your server" error from Fix Common Problems.

 

I have mcelog installed, and I'm guessing I can view the output from Tools > System Log (attached). The relevant portion seems to be this:

I'm running on a Supermicro server with dual Xeon E5-2670 v2 CPUs and ECC RAM. Everything seems to be working fine though. If I didn't have that error I'd have no reason to think anything was wrong.

Looks like a corrected RAM error, check the system/IPMI event log, there should be more info there on the affected DIMM, then remove/replace it.
