I'm a little late to the party but I have access to a Beagle 480 USB sniffer and all flavors of Netduino.  If any debugging assistance is required, I'd be happy to help out.

Sounds like an awesome time

Your timing is perfect. Can't wait for mine to arrive! Thanks guys!

Thanks Chris! I have WireShark installed but I don't have access to the shared host's OS nor do I know how to monitor the traffic from the N+ using it. I moved my test loop into the SocketExample you recommended (much smaller deployment) and it locks up at 561 iterations with no output. I'm going to try to access some local web services to eliminate the possibility of a server side issue.

Same exact failure with using sockets and a POST. 563 inserts, then locked.

private static void TestSockettPost()
        {
            int numTests = 1000;

            while (numTests > 0)
            {
                //write test data and show LED
                led.Write(true);
                Thread.Sleep(250);

                try
                {
                    IPHostEntry host = Dns.GetHostEntry("www.SERVER.com");
                    IPEndPoint endPoint = new IPEndPoint(host.AddressList[0], 80);

                    using (Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp))
                    {
                        socket.Connect(endPoint);

                        using (NetworkStream ns = new NetworkStream(socket))
                        {
                            //POST /somepage.php HTTP/1.1
                            //Host: example.com

                            //Content-Length: 19

                            byte[] bytes = System.Text.Encoding.UTF8.GetBytes(
                                "POST /PATH/FILE.php HTTP/1.1\r\n" +

                            ns.Write(bytes, 0, bytes.Length);

                            Debug.Print("POST done");
                        }
                    }
                }
                catch (Exception ex)
                {
                    Debug.Print(ex.Message.ToString());
                }

                //hide LED
                led.Write(false);
                Thread.Sleep(250);

                numTests--;
            }

            Debug.Print("Test complete");
        }

This just seems crazy to me. Anybody have any idea what could be going on or any input on how to troubleshoot?
