When the application close a socket, the system may delay the actual release for a defined time that you can configure. During this time, the socket is in "close wait" state until the communication resources are fully released. I don't remember which registry key defines this for windows, but the value default may be minutes. In fact, 8 invocations don't seem to be enough to consume all the numbers. I have experienced this kind of problem with some performance testing clients that can quickly use all the port numbers... In your case, more probably, the problem cause will be in your http server or client... and for that i have no idea... Sorry.
