I have the following script running every minute in cron with this
line:
/root/test-service.sh mythbackend mythbackend mythtv-setup

It checks every minute if the service with the first name is still
running and if also the program with the third name is not running it
restarts the second name. This way it won't restart if I have
mythtv-setup running. You only have te change the restart line to the
one for your distribution as this is Gentoo style. And it also logs
any restart.

#!/bin/sh

# Primair te testen Service
if [ "$1" != "" ]; then
        ps -C $1 > /dev/null && exit 0;
else
        echo Geef een Service to test
        exit 1;
fi

# Een eventuele Secundaire service
if [ "$3" != "" ]; then
        ps -C $3 > /dev/null && exit 0;
fi

echo "`date +%Y-%m-%d\ %T.%-3N` $1 not running" >> /var/log/Service-restart.log;
rc-config restart $2
exit 0;
