We are trying to process a set of messages in the message broker. Strange thing that is happening is,

When we process them, sometimes, all the messages gets thru the broker. When we rerun them again, few messages are lost and not able to trace them. Not sure, where these messages are going.

Any suggestions would help in terms of debugging. (using MQ 6.0 and WBI 6.1)

Thanks
Vivek

My answer would be there is no possibility of loosing the messages in mq (where broker process) them at all.

The messages should be atleast in a Dead letter queue(SYSTEM.DEAD.LETTER.QUEUE default queue) or else in Backout queue if there is one defined for Input queue .

Hi,

First you should use debug -trace level for you EG. And then try to re produce this behavior and then get through all details of your flow execution to see what happened.

Perhaps you have shortage on your error handling or you are producing empty messages that are not putted to q's or propagated to the mqoutput node or something else on your flow.
