You can use Microsoft Platform SDK functions to get the heap size at a specific point. If get the heap size at point A in your code, and then again at point B, you can see how much it has grown. This might help you isolate here memory growth occurs.…

That is because your web application has a memory leak. A common issue are "PermGen" memory leaks. They happen because the Classloader (and the Class objects it loaded) cannot be recycled unless some requirements are met (*). They are stored in…
