Don, Thanks for your response, and thanks to Doug White for his response too. I got no other information on a serial console or on the regular VGA console other than syncing disks and the usual shutdown messages. I removed all memory and tried new memory in both 2GB and 4GB amounts. I have removed both processors in turn. Neither of these helped at all. I downloaded a copy of 5.2.1 and installed it onto the machine and it seems to be operating smoothly, for the moment. Once I was able to keep the machine running under 5.2.1 for more than 5 minutes, I downloaded and installed memtest and ran it. It is behaving a little oddly. It will run if I specify 4M of memory, or 128M of memory, but gets an immediate page fault if I specify 512M, 1G, 2G or 4G of memory. Coincidently, it gets NO errors when run under 4M or 128M. I suspect this might be because I have an "old" 5.2.1 kernel and userland. So, just to be sure, I am now cvsuping my /usr/src and I'm going to do a make (build|install)world and I'll rebuild the kernel for good measure as well, just to be sure. Once all that is done, I will re-run memtest and see what happens. Thanks for your suggestion!
