SocketException Broken pipe receives when the server is under load (Spring AMQP) - spring

Question

We are using Spring AMQP 2.8 with RabbitMQ 2.8.7 version. We are building our connection factory as below.
<!-- RabbitMQ Local connectivity -->
<rabbit:connection-factory
id="localWhispirConnectionFactory"
addresses="${system.local.rabbitmq.host}"
username="${system.local.rabbitmq.username}"
password="${system.local.rabbitmq.password}"
connection-factory="rabbitWhispirLocalFactory"/>
<!-- Heartbeat configuration every 10sec -->
<bean id="rabbitWhispirLocalFactory" class="com.rabbitmq.client.ConnectionFactory">
<property name="requestedHeartbeat" value="10" />
</bean>
But when the server is under load, we received the below exceptions. Tries several ways, but appreciate any comments to overcome this issue.
2015-04-20 12:01:00,174 INFO [SimpleMessageListenerContainer] Restarting Consumer: tag=[amq.ctag-wfazQuIuS-BM-CosxP_2GJ], channel=Cached Rabbit Channel: AMQChannel(amqp://whispir#10.50.50.128:5672/,62), acknowledgeMode=AUTO local queue size=0

There is no such version (2.8) of Spring AMQP. Currently, the latest version is 1.4.4.
Check the server logs to see if there are any clues there.
That said, 2.8.7 is a very old broker; I am quite sure the rabbitmq guys would recommend upgrading to a more recent version, currently the latest is 3.5.1.
