We are seeing an issue where using SDBM hash-type that the last server in the pool is getting 100% of the traffic and the first server in the pool gets 0. We also tried adding a 3rd server and the last server still got all the traffic. All weights were 1.
A config sample: backend VIP http-reuse always option httpchk GET /server-status HTTP/1.1\r\nHost:\ haproxy balance source hash-type consistent sdbm default-server inter 2000ms fastinter 250ms downinter 1000ms fall 1 rise 2 slowstart 10s server SERVER1 10.0.0.115:8080 check namespace haproxy server SERVER2 10.0.0.116:8080 check namespace haproxy server SERVER1:backup 10.0.0.115:8080 backup namespace haproxy server SERVER2:backup 10.0.0.116:8080 backup namespace haproxy We were able to resolve the issue by using sdbm avalanche. Is this a known issue or a potential regression? Thanks so much for the help!
