Not all messages will be consumed when optimizeAcknowledge is true
------------------------------------------------------------------
Key: AMQ-3664
URL: https://issues.apache.org/jira/browse/AMQ-3664
Project: ActiveMQ
Issue Type: Bug
Reporter: Matthias Wessel
Priority: Critical
I make performance test with activemq. When I set optimizeAcknowledge = true I
get a dramatic performance improvement, but when I shut down the producer the
consumer does not acknowledge all messages! If I stop the consumer and then I
start the consumer a second time the consumer recieves messages again and again
not all messages will be acknoledged in the queue.
I am using camel 2.9.0 to produce and consume the messages.
I am using the consumer Template with asyncSendBody.
The following route is configured in the camelContext:
<camel:camelContext id="camelContext">
<camel:template id="producerTemplate"/>
<camel:consumerTemplate id="consumerTemplate"/>
<camel:route>
<camel:from
uri="jms:queue0?concurrentConsumers=3&maxConcurrentConsumers=10&asyncConsumer=true"/>
<camel:to uri="beanConsumer"/>
</camel:route>
</camel:camelContext>
The config for the ActiveMQComponent:
<bean id="jms"
class="org.apache.activemq.camel.component.ActiveMQComponent">
<property name="connectionFactory">
<bean
class="org.apache.activemq.pool.PooledConnectionFactory">
<property name="connectionFactory">
<bean
class="org.apache.activemq.spring.ActiveMQConnectionFactory">
<property
name="optimizeAcknowledge" value="true"/>
<property name="dispatchAsync"
value="true"/>
<property name="sendAcksAsync"
value="true"/>
<property name="useAsyncSend"
value="true"/>
<property name="brokerURL"
value="nio://138-ham-de:61616"/>
<property
name="useDedicatedTaskRunner" value="false"/>
</bean>
