I recommend first identifying any cause of slow consumption (especially DLQ - they are notorious) and taking action to eliminate the slow consumption.
For example, a camel route that consumes from the DLQ and logs the messages is a good way to keep the DLQ from acting as a message store - as long as there is no need to reprocess the message. If there might be a need to reprocess the messages, find a good store (not inside AMQ) and put them there. Hope this helps. -- View this message in context: http://activemq.2283324.n4.nabble.com/kahadb-cleanup-problem-tp4677917p4687826.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
