This is the classic BSD mystery problem. I have no idea why this
happens, but it has affected every older system with borderline RAM that
I have seen on BSD, in versions of Minivend from 2.03 all the way
through Interchange 4.6.x.
I believe it is related to signals and Perl, but I cannot be sure. If
you run in a debugging environment, you will probably see an "out of
memory!" error. In any case, I am betting it affects everything prior to
Interchange 4.7.x on BSD unless you have plenty of RAM, and sometimes
even then on a busy system.
