Been running the system since this was posted and I've not had a single problem, so the issue seems to be related to softdep. Someone told me they had experienced a similar problem and that it was introduced sometime after 4.1. I will try installing 4.1 and see if I can reproduce the problem described above. If the problem does not show on 4.1, how should I proceed? I suppose a "binary search" between versions is one way; i.e. try 4.2 next and if that fails, try the development version between 4.1 and 4.2 (cvs checkout at specific dates) and work my way toward the exact date the problem was introduced. Does this sound like a reasonable approach? Anything you'd like to add to help me pinpoint the exact location of the problem (if this actually worked on 4.1 or earlier, that is)?
