SYMPTOMS

On a Microsoft Windows CE 4.2-based device, an application that calls the recv function shuts down and then reconnects the same Windows (Winsock) socket 256 times in succession. After the application reconnects the socket for the 256th time, the application calls the recv function, but the recv function does not respond. When this occurs, the application stops responding and the socket does not send the FIN signal to the remote end of the socket connection.
