IOPn.MtcMon Fault Handler status: CEx has reported n memory error(s).
Variables x – the ID of the CE reporting the errors
n – the number of memory errors reported
Severity Error
Description This error is reported periodically when the CE contains Error Correction Code (ECC)
memory and reports either recoverable or non-recoverable memory errors.
Recoverable errors generally do not compromise CE operational integrity; however, they can
become problematic if they occur on a constant basis or if they are accompanied by non-
recoverable errors.

Hardware/Software This message indicates a hardware error.
Action You need not take any action if the error occurs infrequently (less than once a week). If the
errors occur more frequently, or if the number of memory errors reported is excessive (more
than 10 in any of these messages), this may indicate an incipient problem in the memory
subsystem, and you should take corrective action as follows:
• Run any memory diagnostics supplied with your system to verify the correct functioning
of the memory subsystem.
• If the problem can be isolated to a particular memory component (DIMM or SIMM),
replace the memory.
• ECC errors can be caused by marginal timing characteristics of the memory components
(DIMM, SIMM, or memory controller) and can be exacerbated by the addition of more
DIMMs or SIMMs. If your memory slots are fully-populated, try removing memory from
one or more of the slots to see if this alleviates the problem. You must shut down the CE
operating system in order to remove the memory.
• If the problem persists, replace the CE.
