I should say the app is hung silently. It won't do anything when I click on any links or submit buttons. So I shutdown the tomcat and startup again, but it will say "java.net.BindException: Address already in use..." something like that. I need to kill the java process manually and startup again. When I look at the tomcat log, it has no expection logged. Do you think it is the memory issue?
