I forgot to give details about my Application and test. These details might give you people an idea about the problem area. In this app. users has to enter login ID and pwd in home page which will be sent to a resource which validates these details, say "LoginValidation" this resource will then forward control to the Main Page of the Application, say "MainPage.jsp" . From main page user can open/ request different pages(modules of application). But my test only involves a request to "LoginValidation" followed by request to main page. In this app. inorder to get data about certain activities happening on the server side into the client browser, we keep on refreshing a hidden frame in mainpage (simply using html meta refresh ) after every one minute, lets call this page as PollServerForData.jsp. To simulate this i added a request to PollServerForData.jsp also in my test plan after request to the main page (that means every virtual user will be requesting the PollServerForData.jsp page after every one minute) This test worked for 1200 virtual users and failed for when tried with more than 1200 users . Will there be any problem for tomcat for maintaining more than 1200 sessions in memory??
