Thanks for your quick reply,
The real issue is, on our application server having the F5 setup, it shows in the task manager processes that some clients accessing the server but in real no one is accessing the server, so can you advise why the clients sessions are been creating and killed automatically on the app server rapidly. hence keeping the server's resources busy all the time. We disabled the F5 like i stated before for some time the sessions were not there but afterwards it again start prompting, another server doesnt have the F5 that is working normally... Thanks in advance..
