CentOS - Oct 2008 - "EDAC i5000 MC0: FATAL ERRORS Found!!!" error message?

Hi List,

We had the following error thrown on console on a PowerEdge server  
running CentOS 5 (64 bit). Googling around didn't yield any particular  
insights. The server crashed a few minutes after this message. Running  
memtester, just to check, didn't find anything; and the box has been  
running for months before this without issue.

I'm wondering if anyone has run across this before, and if so, if it  
was software (CentOS) or hardware (PowerEdge / PowerVault) related?

Oct  8 12:19:35 someServer kernel: EDAC i5000 MC0: FATAL ERRORS  
Found!!! 1st FATAL Err Reg= 0x4
Oct  8 12:19:35 someServer kernel: EDAC i5000 MC0: >Tmid Thermal event

channel-b= 3 labels "-": (Branch=1 DRAM-Bank=0 RDWR=Write RAS=11802  
CAS=0 FATAL Err=0x4)

Thanks!

IIRC the EDAC i5000 is the memory controller of the server, and it
looks like something went wrong with a DIMM and that is probably why
it crashed. So it looks like you may have a (intermittent) hardware
issue.
