No data was received from host!

[p1 at fhri.org]

Most are just generic checks, like NSClient version, Uptime, Drive
Space, Memory Usage, several processes and services, etc. It's a Windows
2000 server host running the NSClient++.  It's hard to catch this while
it's happening because it only lasts a few minutes and I'm never here
when it happens.

I started slowly transitioning from using check_nt to check_nrpe and the
responses vary between the two:

check_nt reports: No data was received from host!
check_nrpe reports: Socket timeout after 10 seconds.

I don't believe it's a network connectivity problem, or the ping check
wouldn't succeed and the other checks wouldn't run.  I guess it could be
a non-responsive system condition, perhaps some process hogs all CPU
cycles or something like that...

Nagios is alerting you to a general problem. Without knowing specifics  
about what you're checking and how, generally speaking the host was  
unreachable, down (if this is a check_snmp check), too busy to respond  
or otherwise non-responsive. You should investigate as the problem is  
almost certainly real. Maybe you have a network connectivity issue or  
problem on those hosts.
