Ooohhhhhhh, I had what sounds to be exactly the same problem with my
hub, albeit I was testing something for StuartP, and a faked up xap
heartbeat message referenced an already used port. My apps went
absolutely nuts over that one!

I can't recall what I did to fix it, but it wasn't that. I'll
implement this fix in mine too.
Elsewhere, for general info ... I've been working on my SliMP3
connector lately. A massive set of changes coming to that once I've
finished testing it this w/e. I'll post about this to the
xap_automation group later though as I'd rather see that group kept
lively.
