Hi, I got a problem. I always see this at catalina.out everytime I stopped or reload the web application, what can I do to stop this ? My Application is Thread based and run behind a web application. When the web application stopped, it will set the stop value of the Thread as true and will dump everything on queue to harddrive. Here is the snippet from the catalina.out
