SYMPTOMS
Network packets are lost when a User Datagram Protocol (UDP) stream is received over Internet Protocol version 6 (IPv6). This problem occurs after a burst of packets arrives.



CAUSE
If the UDP fragment queue becomes filled with incomplete packet fragments, all new UDP fragments are discarded until the earlier fragments are discarded. Typically, it is better to favor the newer packets over the older incomplete packets in this situation.
