Cron jobs and crashes

Question

I have a script that I wrote to backup a server at midnight every night. It uses rsync to perform the backup. The past two nights it has run it seems to cause the server to crash. I used the Terminal to setup a cron job to run the script. Does this sound like a serious error or am I doing something completely wrong, or should it maybe be done at a different time? I looked through the logs and the kernel seems to panic and call crashdump or panicdump.
The system in question is a Mac Mini if it makes any difference. If anyone would like I could post the script.

Here is the script file. I tried changing the time the script is run from midnight to 1AM and it ran the problem was that it ran about 60 times!!!!
Is this a problem with the cron job because I see no problems with my script. I can successfully run it from the command line.
