Well, we are still attempting to recreate the problem.  It isn't
something as simple as someone coming in over a tunnel with a small
MTU with a larger advertised MSS.  There is some "magic" that must
happen to actually put the unit in this state.  We ran for 9 hours
before and 9 hours after the hiccup without any problems.

So it is going to take a while before we are ready to test this again
live.  The sooner I can recreate the problem, the better, though.
