No response from remote host？
No response from remote host？
There're hundreds of hosts being monitored, but only one host that sometimes will not response, what could be the possible reason?

Re: No response from remote host？
The alarm error (if I recall correctly) is due to a certain portion of the code running for too long. As a failsafe against code running forever, it can bail out after a certain amount of time. That looks like what is causing one of these errors. The other looks like a networking timeout in general (No response from remote server). Since it is working some of the time but not others I would try and see if there is a faulty networking connection between your Nagios server and 172.17.1.82.
