Hi,
We are faced with a weird problem here. We have a flow which does some validations on the incoming message. These validations are done using agrregation with the aggregation reply queue also in the same flow.

The issue we are having is that when we attach the debugger and test the flow everything goes picture perfect.
However if we detach the debugger and test the same the execution group abends with a dmp file being created.

Our config here is toolkit 6.0 with the broker running on XP.
By the way the only thing i could make out form the abend file created was "access Violation- could not read <some mem loc name>".

We have tried, restarting the broker, machine to no avail. Any inputs to this would be really helpful. Do let me know if I need to provide any more details.
Regards,
Anoop

You should apply the latest broker runtime fixpack.

And the latest broker toolkit fixpack.

Hi,
Just fixed the issue. The problem was that after receiving the aggregate reply, the aggregated reply was being propagated till the point where a new message was being created (and this ewas just before putting it on the output queue).
When the code was changed so that the output of the aggregate reply node was used to create a valid MQ message (with MQMD and Properties) in a compute node just after the aggregate reply node, the problem stopped.
However I cannot still finda reason why this scenario worked when debugger was attached and not when the debugger was removed.

Regards,
Anoop
