hi Assuming your sessions use the default web way , then yes adding a Cookie Manager is sufficient. However this is configured in your application (whether it uses cookie or url rewriting or both) and you need to determine this for your app. This however should have no bearing on your current problem unless you aren't logging out the user at the end of an iteration or whateve, causing your application to have many sessions that it cant inactivate till timeout, but that would manifest itself as an out of memory.
