JBoss version = 4.0.1 SP1 Hello there! We're using JBoss JAAS support in our application. After we deploy our application in production environment and with heavy load (~1000 concurrent users) login authentication stop responding. Users that are authenticated can use the application, but new users do not get a response, the request is timed out before they can login. This causes a huge queue in our tomcat, it shows that every single one of the 900 connections available are waiting for a response from j_security_check. It seems to be a deadlock somewhere. Could someone point me to the right direction? We are using a 4x processor machine with plenty of RAM (we are not having any problems with memories or GC) also we have 500 connections to the DB, no problem with connections either.
