the plex_stop_postcmd function in /usr/local/etc/rc.d/plexmediaserver attempts to kill any leftover child processes, but the kill command runs whether there are any or not. This makes it run without input if there are no processes to kill, making it return an error if you restart the plexmediaserver service. It's benign but unsightly, and I think it should be adjusted a bit to test if the variable is empty before trying to kill it. Something to the effect of:


        if [ -z ${_PLEX_CHILDREN} ];then
            kill -9 ${_PLEX_CHILDREN}
        fi
