I use jboss v.3.2.5 and 3.2.7 If user use web only one, process of web will complete. But if user 10 - 20 person use, process will slow hang. ** see in "Tomcat status" have some process "Time" will increase continous and CPU Usage will upper to 100% in soon. I try to "twiddle" command for unregister that "HttpRequest" which it can unregister but CPU Usage don't low. Look like it isn't right way to do. please help me for this problem, thank you.
