Thanks for the ideas.  strace seems very helpful, and I'm trying it
out now, trying to catch a failure in progress.  Unfortunately, the
problem is anything but repeatable: I've fed the app tens of thousands
of requests (both in one thread and split over several to increase the
transient load) in a short period of time without bringing it down.  I
just have to wait!

It looks like I'll need to make quite a few changes to run the code
externally, but it ought to be informative if I can do it.

Thanks again,
Paul.
