Nagios to lazy to check?

[Sand Philipp]

Hi guys!

I'm using the Nagios 2.0a CVS release running on Fedora Core 2. The currently runs at an avarage load of 0,1 (2 Processor 1,4GHz, 2GB RAM, Ultra SCSI Harddrives)
To get my performance Data into a MySQL 4 DB I'm using perfparse in daemon mode. Currently I run about 280hosts and about 1200service checks.

My Problem is, that Nagios won't check the most of the Services. When I look at the Scheduling Queue, and try to find out when the next check will be, everything looks proper (all checks within about 1hour). But when I look at the times, the last check had been, the most checks are older than 1 day, even when they are regularly checked every 5Minutes! Some checks even haven't been performed because I added them 1-2days ago. The Next Scheduled Check is in about half an hour, but this time is always raising...as if nagios is to lazy and simply schedules the tasks more and more into the future just to don't do the check...
I already did a nagios -s it said everything looks fine. The Service inter-check delay method is SMART Average service check interval is 9327.91sec !!! Thats about 150minutes, event though most of my checks are in about 5minutes regularly.
I already checked if there is a second nagios accidently running...
What can I do? 

here's the complete output of nagios -s
