Windows, Broker 6.0.2

What is the best way of breaking out of a tight loop in Message Broker after a programmer made an error? I find that a controlled stop of the Message Broker service does not stop the broker.

Thank you.

What I did was end the DataflowEngine process using Task manager. Not sure if this is the only way.

Thanks...that is half the solution. Now, when you start the broker again, this tight loop starts again? How do you prevent it from starting?

Hi francoisvdm,

Clear the Queue while the broker is stopped.

Regards.

All good and well if the trigger for the message flow is a queue...but what if the trigger is a timer node?

Ahh, yes, very good point, and no, not the control infinite loop problem

1.Close the tool kit,
2. Kill the process from Task manager


a. DataFlowEngine.exe
b. Javaw.exe
c. bipbroker.exe
d.bipconfigmgmgr.exe

3. clear all the queues
4. Start the broker and config from services
5. open your tool kit.
This should fix, if not fixed restart you system and follow the steps again.

Have fun...
