Hi Lukas, I did try increasing "timeout http-keep-alive", without any effect.
I'm attaching a tcpdump from the client side. For this capture I had the client timeout at 10 seconds rather than 5, but the effect is the same. You can also see that, even though the client timeout triggered, the server was allowed to send a final response before the connection closed. For your information, 10.9.35.100 is the client, 10.9.35.32 is haproxy and 10.9.35.34 is the backend. I'm also attaching a tcpdump of both frontend and backend traffic, this time with a client timeout of 5 seconds.
