Actually, my app isnt in production yet. In time, i'm just tunning jboss before that. so... im using jmeter to stress my aplication and a have to achieve 300 simultaneous access, but for now when it takes 120 the error appears. Im using 2 JBoss. Each JBoss have 1 instance running. In other server i have 1 Apache Web Server(mod_cluster) and the PostgreSQL. In my datasources i have a max-pool-size with 500(for each JBoss instance, so i have 1000 connections). PS: In PostgreSQL, has no limit connection. Any help? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/604556#604556] Start a new discussion in IronJacamar at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
