Using Camel ActiveMQ component to send messages causes many TCP connections to be reestablished

Issue

With a camel route like that below, we see many TCP connections being created and torn down to mq-broker2

<camelContext id="transactionTestContext" xmlns="http://camel.apache.org/schema/blueprint">

       <route>
           <from uri="mq-tx-broker1:queue:input?acknowledgementModeName=SESSION_TRANSACTED&amp;disableReplyTo=true&amp;preserveMessageQos=true&amp;concurrentConsumers=1&amp;maxConcurrentConsumers=1&amp;IdleTaskExecutionLimit=1&amp;maxMessagesPerTask=1"/>
           <to uri="log:com.example.mq?level=DEBUG&amp;showExchangeId=true&amp;showProperties=true&amp;showHeaders=true&amp;showException=true&amp;showBody=false" id="to8"/>
           <to uri="mq-broker2:queue:output.GW02?preserveMessageQos=true&amp;includeSentJMSMessageID=true" id="to9"/>
       </route>

    </camelContext>
