I have been analysing the tcpdump a between 1.4 and 1.5. The main difference I see on the response that haproxy send back to the GSS is the TCP Segment Length. In 1.4 the TCP Segment Length is 0. In 1.5 the TCP Segment Length is 477. Is anyone aware of any changes in haproxy between 1.4 and 1.4 around this area or who/how this segment length is controlled?
It depends what the protocol (HTTP) is exchanging. You may just look at the wrong packet packet in 1.4 trace though. The GSS would have to consider the proxy dead if all TCP packets from haproxy would have segment length == 0, so this doesn't really make sense.
We need to see those capture files (the .cap file tcpdump -w generates). Make sure the entire packet is captured (tcpdump -s0).
Thanks, Lukas
