Why do I get these socket timeouts?!?!

This is the check_nrpe timing out.  There are 3 or 4 timeouts to check
--

1)Service checks have a global timeout in nagios.cfg.  This is usually
about 30sec
2)check_nrpe has a timeout specified by -t.  This is usually 10sec.
3)The remote nrpe agent has a timeout, command_timeout in nrpe.cfg.
This is usually about 20sec.
4)The plugin being run remotely may have its own timeout specified on
the command line.

Normally, (1) should be the largest number. (3) should always be greater
than (4), and (2) should be greater than (4).  (3) should be larger than
the biggest (4) you have.  This will mean that you get timeout messages
from the plugins rather than from the Nagios server.

In your case, the timeout is coming from (2).  This would normally
indicate that your remote NRPE is having problems, but it may also mean
that your (2) timeout is smaller than your (3) or (4) timeouts.

On our server, (1) is set to 60sec, (2) is usually 20sec, (3) is 19sec
and (4) is 10sec.  This means that we receive more helpful timeout
messages, as we know at which point the problem is.
