Please post your command definition, including NRPE
configuratino for same.  It sounds like you aren't executing the
plugin you think you are, or there is a wrapper that is losing
the return code somewhere along the way.

Common example:

#!/bin/sh
check_http ....

if [ $? -ne 0 ]; then
	echo oh no!
fi

The above always returns 0 since the script will end up
returning the exit code of echo if $? is not 0.  It is good that
you are checking $? while testing the plugin, so it sounds like
it is something upstream of it.
