I managed to clear the journal logs on those queues mentioned. The daily (earlier) journal logs file size is about 10GB.
The journal logs only get cleared when concurrentStoreAndDispatchQueues is set to false. However, my producer application ( runs another ActiveMQ server), active non-durable subscribers messages get piled up due to the slowness in message consumption on my end. I am running with 16 core cpu Intel on Linux server with 25GB heap size, and i am using SSD disk on mKahadb. What is my option available - besides setting off persistence ? -- Sent from: http://activemq.2283324.n4.nabble.com/ActiveMQ-User-f2341805.html
