I was running a simple script and the system became unresponsive. I went to the console and couldn't get it to respond, so I had to POWER OFF! Ugh!
(Note: this script, get-backup, ran fine on a CentOS 4.5 system)
Looking through /var/log/messages, I see:

Ideas as to a methodology to diagnose the problem?
You are out of RAM. Did the other system have more RAM or swap available? Also, if your backup is rsync based, it needs to put the entire directory listing for the transfer into memory before it starts with a certain amount needed per file. Perhaps you can break the runs up into smaller sections.
