FW: Service Check Timed Out Error

[Andy Shellam (Mailing Lists)]

My apologies, I'm suffering from a 60-minute lag on SourceForge's 
mailing list for some reason - I'd got 2 replies from David before this 
so it looked like you hadn't copied the list in.

Sorry!

Now onto this e-mail...

As long as check_nrpe server-side can talk to nrpe client-side, you 
should be OK.

If you can run check_nrpe from the server as the Nagios user and you're 
getting a valid response back OK, it seems Nagios is refusing to run the 
plugin and get it's output correctly.
What is the actual error reported in Nagios? 

Also try: shut Nagios down, clear out the "/usr/local/nagios/var" 
folder, and re-start Nagios - you'll lose any previous states (if you 
use the keep state functions) but it'll force Nagios to re-build it's 
objects cache and re-check the services - if you're still getting the 
error after that, something strange is amiss.

Regards,

Andy.
