Oh, I hadn't seen that page. Unfortunately, not many implementation details, and the focus seems to have been on OpenVZ/Vserver, which is quite different than a Paravirtualized Xen. I'm still troubleshooting the problem. Now I'm back from exactly 16k to exactly 12k of data before the connection stops, and saw a bit more of what happens : The real server and the director continue answering, but the client sees all further packets as a different tcp connection. For instance, my local stateful firewall drops and logs all of those further packets. I don't know if I'll be able to figure out why. It does seem like a connection tracking problem somewhere on the Xen Host (dom0), or maybe the Xen guests (domU), but I doubt it. BTW, reproducing the problem seem pretty easy if anyone wants to also enjoy the fun of debugging the issue :-) All it takes is a working Xen setup on a machine with 2 NICs.
