DV/X doesn't seem to be very robust to its own memory usage, although
you can limit usage by other programs (if they're well-behaved).
    I would second Jim Dai's analysis.  I don't use Motif, I use the
DV/X window manager, so I have a couple of extra MB available on my
8MB total machine.  I found that either Maple or GCC (on small test
programs, haven't been doing real work recently) alone worked fine,
but that they wouldn't load together unless I restricted the memory of
the first one in.  Then I'd have problems with the window management
unless I restricted the second one loaded to a certain amount of
memory.  I don't know how much you need left over; I just made sure
there was 1 MB which seems to have fixed the problem.  Since I don't
normally run both programs together (I was curious to see what DV/X
would do), I haven't tried to narrow it down.
    Obviously this solution forces your programs to do a lot of
paging, but I don't see how that's to be avoided with several large
programs doing big calculations.
