Have you ever ported to a 80386 box before? Unlike the 3b2 and other machines
the 386 in unforgiving on null pointers. Perhaps there is minor bug or
something in the code.

On UNIX System V/386 Release 3.2 (I believe SCO UNIX is a variant of this)
SWAP should be about 15% of disk or perhaps in your case 12 meg (1.5 of ram).
As a side note, SVR4 would required twice ram from swap but thats a different
story.

You can run:
# swap -l
# sar -r
Look at the book: System Performance Tuning by O'Reilly and Associates, Inc
