Description

We have a Spring boot + Camel JMS + Activemq Client based consumer connecting to the Artemis 2.27.x broker and consuming messages. When there is a high inflow of messages to the queue where the openwire consumer is connected, the consumer count on the queue increases more than the actual number of consumers connected to the queue, and these invisible or unreleased consumers block the actual consumers from consuming the message. The issue can be replicated on Artemis 2.28.0 as well.
There was no issue in Artemis 2.26.0.

When then same application with a similar load is tested on Redhat AMQ 7.11.0, the issue does not occur.
