Hi Brad.. I'm in about the same state as you are, except that my C isn't good
enough to actually search the source. :)

I've got 13 hosts being checked for a total of 66 services (still evaluating,
so I haven't plugged in everything yet).. and I've found that some instances
of Nagios will fall behind by hours as well.  It seems like restarting nagios
periodically will clean up the scheduler for a little while, but it doesn't
last forever.

My current instance is only about 25 minutes behind, but that's unfortunately
the best that I've seen it lately.  It's been running for about two days now.

I'm also running a fairly default configuration -- if anyone's interested,
check my last post on the subject for my full nagios.cfg (or, I can forward it
to anyone who'd like to see it).  Someone earlier indicated that if Nagios is
behaving this badly it's likely something wrong in my config file, but he
wasn't able to find any problems in my config either.

I originally noticed this problem when I decided to test Nagios' ability to
send one report of a host being down rather than a dozen reports of all its
services being down.  I powered off a machine and waited... 36 hours later,
three of the services on the host were still being reported as 'ok' since they
hadn't been checked yet.

If you come across anything, I'd really love to hear about it.. Nagios looks
great, but if it's unable to check services in a timely manner I won't be able
to use it.
