The CPU fan was = fine, no dust. The machine is cleaned every 6 months so I didn't expect = that to be the cause. Adding a new NIC changed the character of the = crashes and the traces were completely different after that. We = replaced the memory and power supply. Neither had any effect on the = crashes or messages. Updated the OS to 9.2 on brand new disks. = Likewise no change in the crashes. Finally gave up and replaced the = entire computer. Problem solved. It must be the motherboard or CPU. = We are taking the unit back to the manufacturer (its local) and they are = going to see what is causing the problem.

It took awhile of reading through a = lot of code to figure out what to do to get them working again. There = is real value in keeping UPDATING and README files current, complete, = and accurate.
