[rabbitmq-discuss] current queue size is always different with a real queue size. actually, it is always same with actual queue size - prefetch size.

[Henry JunYoung Kim]

additionally, this is an initialization code for channels.

        channel = ConnectionManager.createChannel();

        

        logger.info("Setting basic.qos prefetch-count to " + prefetchCount);

        channel.basicQos(prefetchCount);


        consumer = *new* QueueingConsumer(channel);

        consumerTag = channel.basicConsume(queueName, autoAck, consumer);

        

        logger.info("Consuming a queue '" + queueName + "'");
