Subject Re: Pending messages on queue is stale or wrong

Torsten, All our brokers are on 5.7.0.

I'm wondering if this is to do with a Stomp client which specifies a
prefetch limit of 200 which processes 200 msgs then disconnects. It is
invoked by a scheduled job manager. I've changed this prefetch limit 1 now
to see if it makes a difference under load this week.
