nrpe sudo issues on a remote box

[Andy Riedel]

I narrowed the problem down to the stop() function in the httpd script. If
you comment out the 'echo' line, the full restart works. My guess is that
since plugins are only allowed to return 1 line of response text, nrpe is
getting confused and terminating the plugin when the first line of ech is
received. Perhaps their is some way to pipe the output somewhere else so
nrpe doesn't see it?

stop() {
        echo -n $"Stopping $prog: "
        killproc $httpd
        RETVAL=$?
#       echo
        [ $RETVAL = 0 ] && rm -f /var/lock/subsys/httpd /var/run/httpd.pid
}
