write a script that checks for processes being dead or gone, then relaunches it. Cron that script.

Just an example for non parameterized script relaunching 7997, should be something like

if ! ps ax | grep "zone . myip 7997 myip"  |grep -v "grep" 1> /dev/null 2> /dev/null ; then
   echo "Zone on port 7997 is dead, restarting ..."
   startzone7997.sh
fi

then add to your crontab :

*/3 * * * * relaunchscript.sh 2>&1 >> ~/restart.log

to test every 3 mins.

Pb is deciding what to restart, if world is down, or one or more zones. Restart, one, all, ... ? Up to you . This is just an idea, i'd be interested in some public script if you set up one.
