Thank you Gary! I changed activemq.xml for my queue (NAM_QUEUE_01) in this way:
<destinationPolicy> <policyMap> <policyEntries> <policyEntry topic=">" producerFlowControl="true" memoryLimit="1mb"> <pendingSubscriberPolicy> <vmCursor /> </pendingSubscriberPolicy> </policyEntry> </policyEntry> <policyEntry queue="NAM_QUEUE_01" producerFlowControl="false" memoryLimit="20kb"> </policyEntry> </policyEntries> </policyMap> </destinationPolicy> and in jndi.properties file (used by the Producer) : java.naming.provider.url = tcp://172.22.123.139:61616?jms.useAsyncSend=false But it doesn'w work :-( Now, no exceptions for Producer and for AMQ too.
