Basing from what I see in Daniel Hartmeier analysis of tcpdump (I honestly did not look at the original, when is has been summerized so conveniently): The server is not telling the client that a packet has been lost. The first two ACKs are correct duplicate ACKs, but the remaining ACKs coming from he server have window adjustments, so the client does not treat them as duplicate ACKs coming from a packet loss. --Mark Tinguely
