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.
