Server auto restart

Ok, for a while after I started my own server, I needed it to restart every so often, to avoid lagginess, and to recconect to the master list. So I asked Avl.:C10ud (ianthetechie) for some help. Use this script he gave me:
#!/usr/bin/perl -w

$checkline = `ps -e | grep dedicated | grep -v grep`;
unless ($checkline =~ /armagetronad-dedicated/) {
system "whatever you use to start your server -d >/dev/null 2>&1 &";
}

Of course changing your username and whatever you use to start your server correctly. I edited this code slightly, if you are using BSD you may need to change "ps -e" to "ps auxwww". Now, save this somewhere, do
$ chmod a+x /path/to/it.pl
so you can execute it, and add the crontab
0-59 * * * * /path/to/it.
Then, when you get this to work, add or change in settings_dedicated.cfg
DEDICATED_IDLE #
# being the number of hours before restarting.

Someone should really re-write this, its a little confusing.
