The memory limit is too low

Answer


1. Change the activemq configuration file /opt/pcm/activemq/conf/activemq.xml as below:
<1>. Add schedulerSupport="false" for broker definition.
<broker xmlns="http://activemq.apache.org/schema/core" brokerName="localhost" dataDirectory="${activemq.base}/data" destroyApplicationContextOnStop="true" schedulerSupport="false">

<2>. Disable the "producerFlowControl" as below:

<policyEntry topic=">" producerFlowControl="false" memoryLimit="1mb">

<policyEntry queue=">" producerFlowControl="false" memoryLimit="1mb">

2. Restart the activemq services.
