I had those problems too a while ago on a UP p3-650 laptop.  Finally I just
newfs'ed the machine and installed the 20001028 snapshot, then cvsupp'ed
to 20001122.  The laptop now works well.  What I saw was processes
forking and forking again until the machine runs out of memory and
swap.  I think it may be some old libraries left over from
upgrades and make world.
