False Negatives

I've run them manually both through NRPE and directly on the host that runs them.  All returns okay.  Exactly the same as all other hosts.  I thought perhaps it might be time delay, so I set the timeout on my check_ssh command to 30 seconds (from the default of 10).  I did the same with NRPE.

Have you run the service check plugins manually to see what it returns?
Is it just an occasional failure?

Long time user, first time emailer...

We have been loving nagios and we've even submitted some source code
improvements.  However, we have a problem with false negatives.  We have
2 remote servers we monitor in which the SSH service is being reported
as down, while the host is being reported as up.  Both of these servers
are operating properly.  In addition, the host check command and service
check commands are identical.  We have 40 other servers which operate in
exactly the same way, yet the SSH service on these 2 is being reported
as down.  Exact same versions of SSH on all servers also.  The only
difference is location.
