Just to give you all a feedback..... Finally I found why JBOSS stops to respond HTTP requests. I found an error in my application where the application code was leaving DB connections starving. When the maximum number of busy connections is equals to the max number of connections, JBOSS/tomcat stops to respond HTTP requests. This application uses hibernate 3x and C3PO. I hope it can help you some day... Thanks, View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4222356#...
