You're the first person I know of that's actually using a number here ;)
If you're not going to use 's' (smart; recommended) here, then I would
suggest trying a number >= 1. You're telling nagios that the initial
checks should be scheduled at 1/2 second intervals when almost
everything about nagios operates at a base interval of 1 second.

If you're going to use a number here it must be >= 1 (documented). This
is my guess for your problem. I'd recommend using 's' and so do the
docs.

http://nagios.sourceforge.net/docs/1_0/configmain.html#service_interleav
e_factor

> max_concurrent_checks=1500

Very high but isn't a problem. On a host that does 1200+ service checks
every 5 minutes I have this set to 150.

> service_reaper_frequency=22

Lower is better here. 10 is recommended meaning nagios will look for
service check results every 10 seconds. I have mine set at 2.

These look fine.

These look fine.

No known issues that I recall outside of SELinux problems on CentOS4. I
don't see how it could be causing this issue though.

I'd check the retention tables in the database and verify that they
don't have any data in them.
