[JDEV] Auto restarting jabberd

We were having a problem keeping the jabberd server running this week so I wrote a script to start jabberd and then login to the server every so often to make sure that it is responding.  If it isn't responding, the script kills jabberd and waits for four minutes to let everything settle down and then restarts jabberd...

This script is released under the GNU GPL and is released as is with no warrenty or implied functionallity.  It will not work unless you change some of the paths and user names to correspond to how you have jabber installed on your system.

run the script with the command:

nohup <scriptname> &

and the log will be saved to the nohup file in the current directory.

If you normally need to have any arguments to the script, add them after the jabberd command in the start_jabber function.

Good Luck!
