Service Check Timed Out in nagios 2.0b1

[Robert Drake]

I'm seeing alot of these for some reason.  Recently we got rid of all
our slow service checks so we changed the interval from 20 minutes to 5.  

We've got 4600 services (4300 hosts).  

Currently we've got 42 hosts down, 4 unreachable.  We've got 64 service
check failures (90% of those being Service Check Timed Out)

The problem is that alot of these timeouts are false positives.  Even
though it takes 2 seconds to check a host (even when down) nagios times
them out.  

The box isn't overloaded, usually the load average is around 1.0.  

With that many service checks spread over 5 minutes you should see about
15-16 processes/sec running.  Instead it fluctuates up and down,
sometimes you'll only see 2 sometimes you'll see 30.  It's running
behind schedule too, which is weird.  It's always run behind schedule,
but I don't understand why it can't make a schedule it can kind of
match.

Here's my nagios.cfg:

log_file=/usr/local/nagios/var/nagios.log

It seems like this question has been asked a few times before, but
nobody seems to have a good answer for it.  Is there a magic command I'm
missing that makes things better?

Thanks,
Robert
