Memory usage grows/Backend connections keep alive

Symptom
Web Dynpro Applications do not terminate when the browser is closed or navigation to other applications/pages is triggered. Thus memory usage grows as well as backend connections and thus database locks keep open until http session timeout occurs (preconfigured to 30 min).

Reason and Prerequisites
A popup blocker, e.g. delivered with the Google-Toolbar, is active and does not allow to open a hidden browser window that sends the request to the SAP Web Application Server. Therefore the "terminate session" is not reveived from the server.
Solution
Please deactivate that popup blocker for those URLs that point to the SAP Web Application Servers and/or the Enterprise Portal.
