Hi,I'm running haproxy 1.8.12 on Ubuntu 14.04. For some reason, haproxy does not reuse connections to backend servers. For testing purposes, I'm sending the same HTTP request multiple times over the same TCP connection. The servers do not respond with Connection: close and do not close the connections. The wireshark capture shows haproxy RST-ing the connections a few hundred milliseconds after the servers reply. The servers send no FIN nor RST to haproxy.
I tried various settings (http-reuse always, option http-keep-alive, both at global and backend level), no luck. The problem goes away if I have a single backend server, but obviously that's not a viable option in real life. Here's my haproxy.cfg: global #daemon maxconn 256 defaults mode http timeout connect 5000ms timeout client 50000ms timeout server 50000ms option http-keep-alive timeout http-keep-alive 30s http-reuse always frontend http-in bind 10.220.178.236:80 default_backend servers backend servers server server1 10.220.178.194:80 maxconn 32 server server2 10.220.232.132:80 maxconn 32 Any suggestions? Thanks in advance,Alessandro
