      Description

      With a transacted consumer on either a topic or queue the prefetch extension increments only. This leads to flow control failing b/c the subscription is never full. Messages can accumulate on the subscription dispatch channel if the consumer is blocked or slow. As a result, memory usage limits can be exceeded for topics.
      There is a similar issue with client_ack mode and prefetch.
