We have written JMS topic listeners to run on several unix boxes. For one QManager, when we kill a subscriber process, the topic subscription never times out and we cannot restart the subscription for that topic.

The time that a QManagers hold onto a subscription varies from QManager to QManager.

Is there a parameter for setting a subscription timeout.

There are various parameters that can come into play in this situation. KeepAlive and Heartbeat Interval are probably the most likely. I also know that the base version of the MQ 5.2 product had some problems with freeing up connections that were fixed in some of the later (CSD4 or higher) CSDs. What version of the code are you running?

I set the HBINT to 1 second on the server channel i was connected to and this seemed to confirm that it is this value that controls timeouts on durable subscriptions.

I emailed this information my team and that was the last I heard of it. We are using MQ v5.2.1 for this client, but will be upgrading the client to 5.3.x in the fall.

Thanks for your response.
