problems with nagios spinning on notification

[David Ford]

When a service goes offline, nagios is supposed to tell nagios ircbot
about it.  The message gets to nagircbot but nagios is stuck in a dead
heat run at 100% cpu on read()

This was about 2.5 hours ago, the time now is +9400 seconds (2h36m)

nagios is doing nothing else but:
