Invalid Arguments exception

[smyang10]

I got this running in a Xamarin Android app, but after a few HTTP requests, eventually I will get an Invalid arguments exception. Below is the stack trace.

at System.Net.Sockets.SocketAsyncResult.CheckIfThrowDelayedException () [0x00014] in <7ccabb856481493484e46c69b5c3b288>:0

After that, the server becomes unresponsive and the app has to be restarted for it to work again. Sample code below:

      var observer = await listener.TcpHttpRequestObservable(port: Port, allowMultipleBindToSamePort: true);
      observer.Subscribe(
        async request =>
        {
          var response = new HttpResponse()
          {
            ResponseReason = HttpStatusCode.OK.ToString()
          };

          await listener.HttpSendReponseAsync(request, response).ConfigureAwait(false);

        },
        ex =>
        {
          // error is thrown here
        },
        () =>
        {
          
        });
