No It means no server will deal with more than 10 connections at a time. If one of them reach 10 connections, then all the new incoming connections will be sent to the other server until it reaches 10 connections. Then connections are queued, waiting for a server to finish to process some requests. The leastconn algorithm just means that HAProxy will deliver the next request to server with the less active connections at the moment he has to choose the server to open the new connection. > > Eliezer > Baptiste
