<DIV>Hi all,</DIV>
<DIV> </DIV>
<DIV>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.</DIV>
<DIV> </DIV>
<DIV>As a test I built another one on a completely different distribution, which also exhibited the same symptoms.</DIV>
<DIV> </DIV>
<DIV>I get a couple of these a day on all the machines, unfortunately they seem to be random and infrequent...</DIV>
