False Negatives

[David Johnson]

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.
