I believe that you get correctable RAM ECC errors, but not entirely
sure.
There is mcelog utility that decodes such messages into human-friendly
descriptions.
The utility is available on Linux-based systems.
John Baldwin has a port of it to FreeBSD, but it seems to be WIP and is
private
so far. Wait and watch John posting decoded text in this thread :-)
It is not private, it is in //depot/projects/mcelog/... in p4. It is
not a
complete port yet though (doesn't support the daemon and client modes for
example).
Details for these errors:
HARDWARE ERROR. This is *NOT* a software problem!
Please contact your hardware vendor
CPU 0 4 northbridge
ADDR 7ff6b0
Northbridge RAM Chipkill ECC error
Chipkill ECC syndrome = fe18
bit32 = err cpu0
bit46 = corrected ecc error

As Andriy guessed, I believe both of these are corrected ECC errors. You
can likely ignore them as a low rate of corrected ECC errors is not
unexpected.
Hi,
A little off topic, but what is 'a low rate of corrected ECC errors'? At
work one machine has them like ones per day, but runs ok. Is ones per day
much?
Ronald.
