I also got the "illegal sumout" and it locked up my machine. It did it
four times in a row at the 6564090 iteration (the lock ups were hard
locks - had to recycle power to recover).
However, I had my pentium-II 266 overclocked to 333, and when I reset
the speed back to 266 the problem went away. I have had it overclocked
for about 5 months now with no problems. I have been running prime95 at
333mhz since 16 May 99. After resetting the speed to 266 I went back to
an older backup file (and lost about 4 hours work) just to make sure I
am still working with good data. Interesting to note -- the average
iteration speed at idle (0.275 sec) remained unchanged regardless of the
CPU speed change. Does overclocking even help?
Maybe this error is a bug, maybe a hardware error, although the latter
seems more suspect in my case.
