ASP.NET Website Memory Usage quite high

Question

I have an ASP.NET website that will hit about 2gb physical memory used within about 3-4 days, which to me sounds really bad. At the moment, I have configured IIS to restart

If your ASP.NET application uses events (and which one doesn't), then you have to make sure you unsubscribe from the event.

Rule of thumb:

If you use += to subscribe to an event, then you need to use -= in the Dispose() method to unsubscribe.

There are lots of resources on this topic, and I've had a bit of pain in applications I've worked in because your run-of-the-mill programmer doesn't realize that events can cause memory leaks.
