I am experiencing a problem with Nagios running some checks on our Citrix servers.
For whatever reason, all of the checks will come up with the response: “Connection refused by host”.
We have checked the server at the time of occurence and all seems fine. No memory issues, no CPU issues etc.
Then within 5-10 minutes the problem goes away.
Any suggestions/ideas would be appreciated.
I am running Nagios 1.2.
NRPE ver. 0.7f/2.0
NSclient ver. 2.01
