It's something strange in your environment. I suspect the Norton Cache/Himem setup, since mode swaps/memory access is less controlled than under EMM386. The Norton Cache may also be a real mode stack hog, or do something naughty. I would try first running EMM386 to see if the presence of VCPI makes it better behaved. You could try to increase the CWSDPMI heap size, but I doubt that would help much. Try another disk cache.
