Many orphaned services

Hello,

Lately I've been seeing a large number of log entries that look like this:

'06-16-2003 02:01:55] Warning: The check of service 'x' on host 'x' looks
like it was orphaned (results never came back). I'm scheduling an
immediate check of the service...'

I currently have the maximum number of Nagios procs capped at 100, because 
setting the value any higher causes Nagios to keep spawning procs until 
the machine dies. 

We are monitoring ~125 machines and ~600 services, using the NRPE plugin 
for about %80 of the checks. 

Is the fact that the services are 'orphaned' casuing Nagios to keep 
spawning procs if set to higher than 100 max? Is a longer timeout for NRPE 
check advisable? (I'm currently using 10 seconds, which seems reasonable 
but perhaps not?) 

Primarily, I'm interested in knowing what can be done to correct his
problem and if these error messages are something that I should be
concerned about.

I'd be happy to post any additional information that might help. TIA.
