Hi,

I've upgraded from MQv6025 to v7001. Since the upgrade I've noticed the new queue 'SYSTEM.DURABLE.SUBSCRIBER.QUEUE' steadily increasing (never decreasing).

We don't use durable subscirbers and the messages on the queue point to 'SYSTEM.JMS.ND.SUBSCRIBER.QUEUE'.

Why would there be a steady build up of messages on 'SYSTEM.DURABLE.SUBSCRIBER.QUEUE'?

because somebody has a durable subscription and is not picking up his /her messages? Does the queue increase depth if you have nobody publishing?
Have fun and read the manuals.

These are the same ND subscribers who reconnected to the broker after the upgrade from 6025. Not easy to co-ordinate all clientapps (lots of them) to stop pub/sub to see what happens to the queue. I couldn't find much additional info on this queue either.
