Hi, I am pretty new to haproxy and trying to do ha setup for rabbitmq.
Setup is pretyt simple: listen rabbitmq 192.168.69.106:5672 mode tcp balance leastconn option tcplog option tcpka server rabbit01 192.168.69.107:5672 check inter 1000 downinter 5000 fall 1 on-error mark-down server rabbit02 192.168.69.108:5672 check inter 1000 downinter 5000 fall 1 on-error mark-down backup Everything seems to work well, but I noticed one strange behaviour. If I gracefully shut down rabbit01, message producer (client) connected to 192.168.69.106:5672 notices broken connection pretty much straight away, attempts a reconnect, hits rabbit02 and all is well. However if I simply "turn off" rabbit01, message producer (client) notices broken connection only in around 30 seconds or so. And while the break is undetected it keeps pushing messages thinking there is still someone on another side. Now, from the statistic report I can see that as soon as I turn off the box, rabbit01 is marked as "DOWN", but its "Sessions Current" is still set to 1? In the logs this comes up pretty much immediately after the hard turn off: Jan 17 17:13:51 prodlb01 haproxy[38459]: Server rabbitmq/rabbit01 is DOWN, reason: Layer4 timeout, check duration: 1008ms. 0 active and 1 backup servers left. Running on backup. 1 sessions active, 0 requeued, 0 remaining in queue. After around 30 seconds, the connection is detected as broken and failover happens successfully. At that time "Sessions Current" is set to 0 fo rabbit01. Tried option nolinger and option abortonclose, but no luck. Any help would be much appreciated... Cheers, Andrei
