This is expected behavior. When a message with a JMXGroupId is dispatched
to a consumer, that consumer is the sole one that will receive future
messages with the same JMXGroupId, until the connection from the consumer
to the broker is broken.

Thanks for the quick response.
I am using ActiveMQ 5.15.10 and we are connecting to activemq using MuleSoft

Hi,
We are using ActiveMQ and MuleSoft in our project. We connect to ActiveMQ
from MuleSoft.
As per the project requirement, we are using JMXGroupId and Queueprefetch
polcy.
We have set Queueprefetch to 1 at the connection broker url like below and
number of consumers are set to 2

Hi Experts,
Recently, We have migrated our application from ActiveMQ-5.4(ServiceMix 4)
to ActiveMQ-5.12.
We were using queuePrefetch=0 in ActiveMQ-5.4(ServiceMix 4) which was
working fine. But after migration to latest ActiveMQ-5.12, queuePrefetch=0
is not working and consumers are not able to

Its the slowest possible way of consuming messages; basically no
message is sent to a client until it pulls it from the broker via a
consumer.receive() call.
i have checked the status of subscribers. all consumers have active state!
what is downside of queuePrefetch of 0?

Use JConsole to look at the active subscribers & their status. Try
killing them to release the block.
