I'm having a frustrating issue. I am trying to do a lights out re-image of a batch of workstations (22). I've noticed that about 3 out of 5 attempts causes the server to reboot.

The tftp downloads slow to a creep then quit and when I investigate the server I find that there is a new boot.msg in /var/log and that the server has rebooted.

I'm not using a multicast session but have been able to image large groups of servers (15-20) before.

Any ideas?

ZENworks Imaging Service version is 7.0.1-4
PXE Services version is 7.0.1-0.
Server is SLES 10.1.
