I changed that value to 504 and recompiled yesterday. Machine seems to
run stable with this. I built some ports without any trouble and today
I ran 'while true; do make -j4 buildworld buildkernel KERNCONF=PE2650; done'
for some hours without any trouble.

What else may I try out? Stress-Test with bonnie++? SCSI-stresser? Any
special tools. Debugging-info?
