    I just did a new test, a little bit more synchronized this time.

    Two new attachments.
    x-server.log - pf said this during the x run
    x.pcap - pcap taken on the client side during x run

    I got no state errors on the client. Both server and client run 6-CURRENT
    from yesterday.

    At least you should have them now, sorry but I got nowhere to host them.
