1238 services monitored here on my busiest collector (dual PIII 800) and
I've not seen those when I didn't expect them. I generally allow a 30
second execution time for most plugins as a buffer though. 

Are your services that you're monitoring taking longer than 10 seconds
to respond to the plugin? If so, you can adjust your plugin timeout and
nagios timeouts appropriately. 

Are you allowing a sufficient amount of time for what you've told the
plugin to do? For example, if you tell check_ping to send 10 packets,
that's ten second right there just for the packets to go out. Then you
add onto that startup time, response time from the remote host and
evaluation.

Could there be network problems contributing to slow response times?
Incompatible speed/duplex settings, errors, full pipes, etc? 

How loaded is the Nagios server? If it's overloaded the plugin may be
forced to sleep longer than it otherwise would and the execution time
would be longer as a result.

Hth,
