Hi, Thanks for the suggestions, have modified the setup to monitor for connection leaks as suggested. In the meantime... server.xml.....max connections = 1200 (normally, the number of jboss threads sits around 600 - around 75 from a fresh jboss start, and then a further 500 or so once I load the application with 500 users) I will drop an update as soon as I have implemented any/all of your suggestions....thanks for the comments...
