I intermittently get the following exception in my .Net WCF Service.
\"The HTTP service located at http://MyServer/TestWCF/MyService.svc is too busy.\"
I just ran into this error, and it boiled down to a simple configuration problem. I had a service up on the exact same port and same interface (mock service). I ran the service with the appropriate command line switch to run the "original" service I intended. The error went away.
