Well, the other people haven't run it nearly as much as I have, so I'm
not sure whether they will run into these problems.

Yep.  I've also noted that some days/times I can run it many times in
a row with no problems, whereas other days/times it fails almost every
time I run it. I'm thinking there may be an interaction with some
other software on my machine that isn't running all the time.

We will be doing a multi-machine distributed run later this month. We
may need to exclude my machine if we can't figure out how to fix the
problem.
