System Crashed when using Mondo Backup

I run a nightly backup at 2AM of our Fedora Core 1 server using Mondo. About
once every two weeks the system will freeze up. It won't process email,
present web pages, and I can't log into it using SSH. The console screen is
blank. We have to cold start server.

The easiest suggestion is to stop using Mondo, but I like the fast recovery
Mondo offers.

So we're trying to figure out how to diagnose this problem and where to
start. Memory, Hard Drive (is new), IDE controller, etc?

Does anyone have any ideas where to start?

Thanks,

This is my script to run Mondo daily at 2AM:

mkdir -p /home/mondo/`date +%A`
mondoarchive -Oi -d /home/mondo/`date +%A` -E "/home/mondo"


Log files don't provide any clues.
