I am trying to test my webapp in JMeter 2.2, but I have a difficult problem. The webapp is used for applying to our organization. It consists of 13 pages, most of which are for data entry. With JMeter, it consistently blows up on the server, about halfway thru the 13 pages, with a Java StackOverflow error. When I test it in a browser, there is no problem. I'm also using the product Badboy for testing. I get no StackOverflow error with that, only with JMeter. Our environment on the server is: Fedora Linux, Apache web server, Tomcat 5.5.17, Postgres database, Java 5.0, Struts, Torque. We use Javascript on the client. Has anyone run into this problem?
