Bug in Nagios orphan-check?!

[Carroll, Jim P [Contractor]]

It *does* seem that you're running out of memory.  Just a guess.

You haven't mentioned how much RAM or swap you have on this machine.  80
nagios processes isn't much, considering I've had quite a bit more than that
in the past.  Granted, I'm also running with 1 GB of RAM and 2 GB of swap.

You might want to consider adding more RAM and bump up your swap space.
