Many Orphaned checkeds

[Samba]

I'm using Nagios 1.1 to check 180 Services on 86 hosts.  The problem I'm
having is there about 20 service checks (mostly pings and check_nt checks)
that usually don't return statuses on the first check.  If I run them
manually as the Nagios user they work fine, every time.  I'm getting errors
in the nagios.log file like:

[1061572439] Warning: The check of service 'CPU Load' on host 'marketsrv'
looks like it was orphaned (results never came back).  I'm scheduling an
immediate check of the service...

If I watch the Scheduling Queue CGI page I can see that most of the services
run on time, but these 20 appear to just hang.  Does anyone have any ideas
on what I can do to fix this?  Is it because I have too many service checks?
Nagios is running on a dedicated P4 with 256 RAM.  I really don't think this
is a hardware issue.  

Another thing I've noticed is that there are a lot of Nagios processes
running.  I restartred Nagios 1 hour and 41 minutes ago and there are over
100 Nagios processes right now:

nagios:/usr/local/nagios/var # ps -ae | grep nagios | wc -l
    118

Any help is appreciated!
