Hi, Maybe your server answered faster before, or you have now much more traffic. HAProxy will maintain the number of connections opened it needs for the amount of requests it has to send to a single server. If your servers are slow to answer, the connections remain opened longer, then you could reach the minconn (and maxconn) faster. The same if you have more users: you have more chances to reach the minconn and to use queues. Cheers
