ups and fork()

I'm running 3.3.7 on redhat 7.2 (on a virtualmachine) and I'm finding
that upon hitting the fork(), ups is just crashing.  Is that normally what
happens?  I suspect that what ought to happen is that ups will step over
that fork() and that process will be spawned, but the current ups will know
nothing about it unless takes steps to spawn another ups or have the current
ups follow it.  Is this correct?  If so, what could cause ups to crash on
a fork()?

I've eliminated system and user memory limitations as possibilities.


here's the snippet, sparse as it is:
---------------------------
pid = fork();
---------------------------

appreciate any input,

Jamie
