Hi, Thank you for the valuable answer. The problem was that instances of my web service increases every time i make a request. Eventhough as the time passes the GC cleans the unused instances it was still a problem. After i change the session scope of the web service to request the problem is solved. The memory goes back to normal level after each request ends. Fatih Güçlü Akkaya
