Hi James Yes I've tried lots of things! However, I discovered that hs8 was not running the Nov 3 kernel (uptime 68 days) so I rebooted this morning, forgetting to check /boot/grub/menu.lst where "default=2" put the same damn Sep 3 kernel up. Users are busy on it until lunchtime, but I'll let you know if it still fails with both servers on Nov 3.
