I've had a similar issue using two Picos one Posting data and one acting as a server. Client posts data (80 characters), server receives and echos data over and over and finally it crashes with the CIPSERVER fail message. I think it has to do with the number (5) of sockets. I though it might be the capacitor on the shim but haven't had time to install them for a test. Wifi.debug() displays the socket information.
