Consumers Being Duplicated
We are using ActiveMQ 5.9.1 over the Azure Cloud. We have a Azure cloud
application that has 4 consumers listening for messages using failover
mechanism . These 4 consumers use message and process these messages
accordingly. The consumers seem to duplicate after a couple of days.
Although it's not always the case, once the duplicate consumers are seen
messages are not been picked up by the consumers anymore.
How can we control and ensure that duplicate consumers are not created?

What are you using to figure out that consumers are duplicated? I've seen
misleading information in the clientConnectors section of the JMX displays
(accessed from JConsole) under ActiveMQ 5.8.0 that sometimes looks like
there are more consumers connected than there really are, because it
appears to show both prior and current connections, whereas the web console
has always had the correct number of currently-connected consumers in my
experience. So where you're looking to make that determination matters.
Also, are you using queues or topics, persistent or non-persistent messages
(and what message store type), durable or non-durable subscriptions, etc.?
More information about your configuration will increase the odds that
someone is able to help you figure out what's going on.
