The socket is just 'sending' data from the Upp app to a Java app.
OK, that explains packets (time for packet to pass from socket to socket is very low, so none get buffered).

The errors were shown up in the Java display app.
That is still very weird. Frankly, given nature of TCP/IP protocol and the fact that U++ side of things is quite primitive, I would start looking for bug(s) in Java app...
