I appreciate the feedback we've gotten regarding our news server  lockup
 problems. It seems to be running relatively OK now, so I thought I'd post
the fix.

I went over and over the SCSI chains ; double checked the internal and 
external cables, double checked the terminator power and that all the
termination was correct. Looks fine. Still crashing.

Scratched my head and said. "Hmm...I wonder if there's a fundamental design
flaw with the termination on this disk?" It's the sort of disk which has a
single jumper to specify whether it's terminated or not (as opposed to a
physical resistor.) Re-arranged the SCSI chain, putting the questionable
disk in the middle and a disk with known-good termination on the end.
Most of my problems have vanished.

The moral of this story, boys and girls, is: Your drive's termination might
not be correct.
