Kernel Oops Problem...

[Scott Bye]

Hi all,
 
I'm not entirely sure this is the fault of Nagios, but I've got a
couple of identical machines here that are all exhibiting the same
symptoms. The boxes have been running fine for about a month or so with
various background tasks, services and quite a bit of code
editing/compilation being performed. Then I loaded Nagios onto them, and
ever since then I've been getting kernel oops's. I've run a memtest and
that came out fine after 100 odd passes, and the operating temperatures
seem fine too.
 
As a test I built another one on a completely different distribution,
which also exhibited the same symptoms.
 
I get a couple of these a day on all the machines, unfortunately they
seem to be random and infrequent...
