Hi Peter, we encountered same problem again but this time no database issues. I will explain in more detail. We are using JBoss 4.2.3 in production. its' using sun solaris operating system. Sometimes server is not responding.we can't open http://ip:8080/ it won't respond for this url. But if we check the status of the server it says server is running? no error messages been logged in the server.log file. Since no error messages logged in the log file, is there any way to find why the server is not responding? Thread dump also, was not useful in this situation as I analyzed.
