The plugin/command you are using to check the host is providing no
command line output but is still exiting with a code of 0 (successful).
Try running the check_command, as the nagios user, exactly as it's
defined, from the command line and then 'echo $?'. The results of the
echo for a down host should be '2'. Chances are you're going to see some
additional error output from ping/check_ping.
There was also a suggestion earlier for another issue to add '2>&1' to
the end of the check_command definition to redirect error output back to
Nagios. If that works as advertised, and I believe it will, that could
be informative as well.

Marc,
indeed there are other issues here.
The check_ping is seg faulting with an error code of 139
./check_ping -H csep0602 -w 100.0,20% -c 500.0,60% ; echo $?
Segmentation fault
139
Which is resulting in a host up message.
Do you have any idea why this would occur on a seemingly random basis? I also manually ran the command for other servers, which also resulted in the same output.
Thanks
Mike
