hi my web application which consists of servlets and JSPs hangs at times. I doubt that it could be because of Stack Overflow problem.I want to use a testing tool to monitor my server's stack usage. Which tool should I use ? I'm using Apache tomcat server.
Thanks in advance

If it is stack overflow, you would get StackOverflowError. You could increase the stack size by using -oss on commnand line to validate this.
You could use kill -3 on unix environment to dump the java thread stack(this should be possible in other environments also and will be perfect to find this problem). This should show you where it is hanging. If you are using VAJava you can use debugger to suspend threads and see where threads are stuck.
