Because this Memory (DIMM 002 - in this case) generated this warning [0C00FFFF Correctable ECC DIMMN] often we will change this memory.
The alarm is generated when the error correcting code (ECC) errors reach the unrecoverable limit. The alarm severity for this warning is minor, in fact this is not a hardware problem, it’s more like a software warning but not a hardware defective.
If you have possibility to try “power off” the server and “power on” the alarm will be cleared.
if the warrning will appear again in few days, replace the memmory.
