Durable Subscriber flashes when monitored
Hi,
We have a durable subscriber from one of our client department that behaves a bit weird. It flashes a lot (basically on and off in jconsole) when jmx monitored using jconsole, I am not sure what the problem is here. All the other subscribers from other departments looks fine. You cannot even click on that consumer on jconsole. Has anyone seen such behaviour. We are on ActiveMQ 5.4.2.
Regards,
P

Spot on Chrisitan,
Torsten was 100% correct (advise spot on as well), the problem was traced to a client's piece of code that used spring DefaultMessageListenerContainer and the cache level for JMS resources was set to "none". So we saw a lot of below on our log files. They have effected the change and everything it looks ok now.
Much appreciated

I have seen this, as Torsten mentioned, when the subscriber is connecting/disconnecting/reconnecting all the time

Any chance you could verify that this particular subscriber is not subscribing and unsubscribing all the time, causing it to get registered/unregistered very quickly?
5.4.2 is fairly old, I would highly recommend to upgrade to the latest version some time soon.
