The netcat 7.94 allows multiple connections over udp (-k/--keep-open) [0], without this option the connection can be closed "unexpctedly". This to keep the test backward compatible make new servers for every UDP connection.
The second issue is that netcat is attempting to listen on IPv4 when the there isn't any server address specified and fails to do so. Add -6 flag to indicate that this is pure IPv6 connection.
