I have a port that (my current theory says) is being closed when it shouldn't, but I'm having trouble isolating exactly where and when.

Am I headed in the right direction, or is there a better way?
Ports are able to raise events. I don't know if any of these are directly useful to diagnose your early close problem, but you may be able to cobble something using multiple events.
