I have master-master replication with mysql. and haproxy configured front of my master-master replication. When I connect my replication via HaProxy, mysql says that "MYSQL has gone away". But when I connect my replication via mysql1 or mysql2 servers no problem.
is there any haProxy config about mysql connection time out ? UPDATE I finally solved. Problem is HaProxy config file's server and timeout values. You can increase this values according to your system and architecture.
