After Upgrade to FreeBSD6.3 my nagios daemon startet to hang. So Service checks were not performed anymore. For some reason the parten forked service processes with a WCPU of 100% taking all the cpu. 

The only workaround was to kill -9 the corresponding pid. This is not of much help since Nagios doesn't repeat killed service checks anymore (or I don't now how). So  
I had to combine a cron script killing these processes (to give you an idea: were are performing about 1000 service checks per 15 minutes. Roughly 10 of which were malfunctioning) and I had to reload the nagios-daemon in order to reschedule killed service checks. 

I tried Nagios 2.10 on FreeBSD6.3 PRERELEASE amd64
I downgraded to 
6.2-RELEASE-p10 FreeBSD 6.2-RELEASE-p10 #0: Thu Jan 17 20:21:26 GMT 2008 

Now everything is working fine again.
