Hm. I've never seen that happen. Can you enable debug logging for activemq-web? I've been adding log4j.logger.org.apache.activemq.web=DEBUG to config/log4j.properties. When a new ajax client connects, you should see a line like: DEBUG | creating new AjaxWebClient in p8v92prp07trmhghrpltw0rh-1294788329515 If you close the browser window and wait a minute, you should then see something like: DEBUG | Cleaning up expired web clients. DEBUG | AjaxWebClient p8v92prp07trmhghrpltw0rh-1294788329515 last accessed 95 seconds ago. DEBUG | Removing expired AjaxWebClient p8v92prp07trmhghrpltw0rh-1294788329515 If you see a message like that 'Removing expired AjaxWebClient' while your browser is still actively polling, that's wrong. Not sure what else might cause the consumer count to drop back to 0. alex
