官方解释:

Total Correctable Errors count attribute file:	'ce_count'	This attribute file displays the total count of correctable	errors that have occurred on this csrow. This	count is very important to examine. CEs provide early	indications that a DIMM is beginning to fail. This count	field should be monitored for non-zero values and report	such information to the system administrator.

查询日志

[root@hh-yun-compute-130125 ~]# tail /var/log/mcelogmcelog: failed to prefill DIMM database from DMI datamcelog: mcelog server already running

This is a harmless warning message. The DIMM database prefill relies on a specific non-standard format of the DIMMs in the DMI BIOS tables. If this format is not used by the BIOS, mcelog will only discover DIMMs as they get their first error (if the CPU reports DIMMs in machine check errors). Please understand for the most part, mcelog should be ignored.
