I have installed the latest version of OSSEC (2.8.1) and I have also enabled email notifications. And I am getting loads of these sorts of notifications saying that there is a Hardware Error and something about mce:
OSSEC HIDS Notification.
2015 Apr 04 20:09:22
Received From: Bath-Towel->/var/log/syslog
Rule: 1002 fired (level 2) -> "Unknown problem somewhere in the system."
Portion of the log(s):
Apr 4 20:09:21 Bath-Towel kernel: [ 1873.680872] mce: [Hardware Error]: Machine check events logged
--END OF NOTIFICATION
So what exactly does this mean? What does mce stand for? And is this apparent hardware error anything that I should worry about?
OS Information:
Description: Ubuntu 14.10
Release: 14.10

Machine Check Exception:
Your computer experienced a hardware error and the kernel logged an event in a buffer. You can use
mcelog
to log and view the machine check events. Frommcelog
manpage:If you didn't notice any crash, probably the error was successfully corrected. Still, I advise you to install
mcelog
to keep track of such events:The events will be logged to
/var/log/mcelog
. You can also run:to query the
mcelog
daemon for errors.
