8.1: a SuSE cronjob hangs all my machines

I have several machines, mostly "barebones" PCs, used as webservers. All
have the "minimal" SuSE 8.1 Pro installation (no GUI).
The only changes I make are: configure the network settings and the apache
settings.
Every night, all machines crash after running this script in the
/etc/cron.daily directory. This and the other scripts areprovided by SuSE
and have not been modified.
/etc/cron.daily/suse.de-backup-rpmdb
When I run this particular script from the command line, my screen goes
black and the machine hangs... so you understand that I can't get any
"echoed" debug output.
I don't really need these backups, but I would like some insight as to why
they are hanging my system! Give me a few tests to run, and I will gladly
debug this sucker. From what I can see, the supporting files needed to
"source" the config variables are present, permissions are good... as
mentioned earlier - these are just as they come from the plain
installation.
Thanks
