FIX: Memory leaks may occur in ASP transactional pages that create COM objects in Internet Information Services (IIS) 6.0

In Microsoft Internet Information Services (IIS) 6.0, small memory leaks may occur when you use Active Server Pages (ASP) transactional pages that create Component Object Model (COM) objects. If the COM object is hosted in a COM+ application, the values increment in the Objects column and in the Activated column. This values increment for the COM+ application in the Component Services snap-in. However, the values do not decrement.

This problem occurs if you call an object that is created by using the Server.CreateObject method, but you do not explicitly set the object to a null value.
