My message broker is putting meessage to a mainframe queue Q1. Broker Queue manager and mainframe queue manager are in one cluster. Message flow is sucessfully able to put the message to Q1 without any exception, basically I do not see any exception I mean no exception because I have very robust exception handling mechanism, but instead of message going to Q1 message are going to dead letter queue of mainframe.
My questions are
1. What can be the reson that message are going to dead letter queue.
2. What will happen to message if the Dead letter queue is full. |

If the messages are persistent (and they'd have to be to go to the DLQ), then when the DLQ is full, at a minimum the channels will shut down.
Each and every single message in the DLQ will have a Dead Letter Header on it.
Each and every Dead Letter Header has a Dead Letter Reason Code on it, that will tell you why that particular message went to the DLQ.

| All the messages are persistent messages. If the chanel shuts down the wat will happen to messages, it will be lost or it will be in xmit q. As i said put did not failed. |

So what is the reason code on the DLQ header?

If the channel shuts down, the messages will remain on the xmitq. If that fills, the puts from broker will fail with a queue full error.
