[rhelv6-beta-list] Errors - OS or Hardware

[Paul Krizak]

That's a hardware error -- the memory controller has reported a (likely 
corrected) ECC error.  You can check the statistics under 
/sys/devices/system/edac/mc to see which dimm is throwing the errors. 
If it's just a few then it's probably OK, but if you're getting hundreds 
or thousdands of corrected ECC errors, then you probably have a 
stuck/bad bit in one of your dimms.

Also check for uncorrectable errors -- any of those and you know that 
data is actually getting corrupted -- bad!!!
