Mine was all default too. Switching to tcp fixed _most_ of my issues.

Yes this is the same for me. The particular client in question just happened
to be the one domu I actually use and needed. If I was to use it as I had
been, it would indeed lock up at some point. I don't think it was triggered
as easily as in your situation though. I'm guessing that if a system locks up
at anytime without throwing _some_ error, then there is a bug somewhere. It
could be coincidence but it seems strange that switching to tcp should have
such an impact.
I have a feeling there might be something being exposed maybe with recent
changes. Well, with any luck ;)
If there are any scenarios you want to throw my way for testing, feel free.
They'll all be domu though, in case that matters.
