Yes, even with that patch.

I'm not sure it's after the final reset. I can add debug code to
make sure it isn't allocated after that final reset.
One clue is the XID is 0, and I don't think that would
happen except by huge coincidence
after the lport has been up for a while. It must've been the first
exchange that was created. It must've timed out but I don't see
any bugs in that path. I can print the xids in my trace, that
may also help.
I've refreshed to the latest patches and am testing it again.
Thanks for thinking about this.
