无法停止ActiveMQ Producer？

Question

I am unable to stop ActiveMQ Producer.

Scenario is: I have set low values for memory usage and temp storage.

<systemUsage>
  <systemUsage>
    <memoryUsage>
      <memoryUsage limit="1 mb" />
    </memoryUsage>
    <storeUsage>
      <storeUsage limit="100 gb" />
    </storeUsage>
    <tempUsage>
      <tempUsage limit="50 mb" />
    </tempUsage>
  </systemUsage>
</systemUsage>

Producer flow control is set to false

<destinationPolicy>
  <policyMap>
    <policyEntries>
      <policyEntry topic=">" producerFlowControl="false"/>
    </policyEntries>
    <policyEntries>
      <policyEntry queue=">" producerFlowControl="false"/>
    </policyEntries>
  </policyMap>
</destinationPolicy>

Now broker has blocked producer and am unable to stop producer, Why is this happening?

Broker Logs say:

Stopping producer (ID: Hidden ) to prevent flooding queue://test.queue.0. See http://activemq.apache.org/producer-flow-control.html for more info (blocking for: 151s)

Answer 1

You have not disabled producerFlowControl for queues, only for topics.

You would need to add something like this:

<policyEntry queue=">" producerFlowControl="false"/>

The link provided by the logs explains the behavior pretty much in detail. Your producer is somehow flooding the broker and the broker responds by blocking for some time.

Answer 2

go to bin folder path from terminal and run the following command:

./activemq stop

Hope it helps.
