>                 Key: AMQ-4235
>                 URL: https://issues.apache.org/jira/browse/AMQ-4235
>             Project: ActiveMQ
>          Issue Type: Bug
>          Components: Broker
>    Affects Versions: 5.6.0, 5.7.0
>            Reporter: Gary Tully
>            Assignee: Gary Tully
>              Labels: configuration, failover, prefetch
>             Fix For: 5.8.0

> two brokers configured with the following policy:
> {code}
>  <policyEntry topic="FOO.>" topicPrefetch="10" />
> {code}
> My consumer will failover to the other broker, if it is no longer there:
> {code}
>             ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory(user,
password, "failover:tcp://xx:61666,tcp://xx:61667");
> {code}
> When this subscription becomes active ( ant consumer -Dsubject=FOO.TEST -Dtopic=true
-Dmax=100), I can see in jconsole that prefetch limit is indeed 10. When I kill the  broker
on 61666, the consumer failsover to 61667. Unfortunately, the prefetch limit has now changed
to 32766. 
> If one configures the consumer to set the prefetch limit:
> {code}
> destination = session.createTopic(subject +"?consumer.prefetchSize=20");
> {code}
> It works consistently, but not having control of consumers, it needs to be configurable
broker side.
