(No output!) Errors in Nagios 2.4

[Andy Shellam]

Hi Brian

Whenever I'd changed the configuration I always used "killall -HUP nagios."

The machine does use the rc init scripts on bootup and shutdown.  
Several times I've kill'd the nagios process so absolutely nothing of 
nagios was running, removed all the state information from nagios/var, 
then used the rc init script to fire it back up again.

I understand Nagios spawns more processes, I just thought it strange it 
would spawn another daemon during a check?

Anyway, last night we had some awful problems on that machine (files not 
being found when they were actually there - probably explaining the "127 
- plugin not found" message.)

I rebooted the machine last night and kicked Nagios off at shortly 
before midnight.  Out of my 17 services and 5 hosts, there are only two 
services that are playing up now - the rest have been in the same 
(correct) state for 15 and half hours now.

The 2 that are playing up still is an nrpe check which executes a 
check_disk and check_swap command on another machine.  The status logs 
of the 2 services since midnight are shown below.

I have no idea where "tcp" comes in, as it's not present in any of the 
commands ("/usr/local/nagios/libexec/check_nrpe -H $ARG1$ -p 5666 -t 60 
-c $ARG2$") - $ARG1$ is $HOSTADDRESS$ and $ARG2$ is "check_endeavour" 
and "check_swap" for the 2 checks respectively.  The NRPE on the remote 
machine for these two commands reads:

command[check_endeavour]=/usr/local/nagios/libexec/check_disk -p 
/endeavour -w 10% -c 5%
command[check_swap]=/usr/local/nagios/libexec/check_swap -w 10% -c 5%

Is it possible this machine is having difficulty reading the 
/etc/services file, hence not being able to map a protocol number?
