I am running sercurity tests on a .jsp web app thats running on a windows 2003 with jboss app server. The tool I am using is AppScan AE which basically tries to exploit vulnerabilities and run some common penetration tests on the app and server. The application makes many requests to many different links within the app directory.
After awhile the testing tool crashes the web app and I can no longer pull up the web app. I get Service Unavailable which I researched and found its a 503 error usually related to overloading the server. E.g. database connections or threads.
Has anyone had this issue or know of a setting where you can change the application pool queue limit?
Since you are dealing with a web based app, you will have to look at the http connector settings in the server.xml of /server/default/deploy/jbossweb-xxx.sar
Look the settings for the threads.
