So if you are using a Netscaler with SLB-PT (IPv6 VIP balancing to IPv4 servers), the entire LB is subject to stop working until they get this fixed.
And this is EXACTLY why we needed World IPv6 Day.
Agreed, right on the money !!
Traffic stats may not say a lot yet due to tunnels and lack of native IPv6 connectivity but finding this type of bugs is a major reason to do live tests, even if the test fails.
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.
