MQ 6.0, WMB 6.0 FP5
I have a msg flow which publishes to a JMS topic on a 3rd party tool. I am able to publish successfully to the topic regularly. But sometimes, after some days, because of some problems/limitations on the number of connections on the 3rd party tool, when it reaches maximum number of coinnections, our mb flow is getting "Connection Closed" error. I agree that this should happen (connection closed) since the problem is on the 3rd party tool.
My problem/concern is that once this problem occurs, my flow is getting hanged (flow shows its in started state, but does nothing). Once they restart the 3rd party tool, we had to bounce the execution group to bring things to normal again.
What I want is to have the msg flow work fine without restarting the flow/execution group.
Hope I have explained it in sensible way here. Has anyone faced this kind of behavior?
Your reply is appreciated. Thanks in advanace.

Are you using the JMSOutput node to do the publication?
If so, you should review the docs to see what it says about how the JMSOutput node handles provider connection issues, and then review your flow implementation and then open a PMR if you don't have a good answer.
It may be that the node doesn't have capabilities to restart the connection if it drops, without restarting the flow.
Or it may be that your flow is wired or configured in such a way that prevents the node from doing this.
If you're not using the JMSOutput node, then review your code to see how to change it to reconnect.

Jeff,
Thanks for the response. I am using JMSOutput node. I have opened a PMR for this. Will update if I get any solution.
