Question

Why are we getting the message EZZ0336I NO LIMIT ON INCOMING UDP DATAGRAM QUEUE SET ?

Answer

This message confirms that the NOUDPQUEUELIMIT parameter has been coded on the UDPCONFIG statement of the TCPIP PROFILE.

The NOUDPQUEUELIMIT parameter specifies that UDP should not have a queue limit. With NOUDPQUEUELIMIT specified, it is possible for inbound datagrams to arrive and be queued to a UDP application's socket faster than the application can receive the datagrams. If so, the amount of data queued could be substantial, resulting in a possible shortage of system storage.

For this reason, set a limit using UDPQUEUELIMIT or by using an IDS Traffic Regulation policy.

If intrusion detection services (IDS) Traffic Regulation (TR) policy is in effect for a UDP port then NOUDPQUEUELIMIT is overridden for that port.
