Sounds like an SCSI problem.  Wrong termination, incompatible drive(s)
or something like that.  Haven't seen this on my system since I got rid
of the ibm spitfire and started using Quantum drives only.

My A3000 was up for 65 days in row, having about 20-25 users logging on
every day.  Then it locked up without any reason while there were no users
logged on the system.  There is a bug somewhere in the kernel and I wish
some guru (hey you German guys, this means someone else but me! ;-) took
the time to locate and fix it.

High system load doesn't seem to crash the system, at least not mine.
