camel aws-sqs route stops consuming messages abruptly from aws queue

HI I am using camel out of the box aws-sqs route to consume our messages from the amazon sqs queue .The configuration we have is as below

    <from
            uri="http://ift.tt/1GxQBlf}}" />
        <log message="Got from SQS Messaging Queue: ${body}" />

here the amazon.sqs.outbound.delay= 2000 and maxMessagesPerPoll=10 .What we have observed in our prod environments in that the consumption does start for some hours but then the route stops consuming messages until we manually stop and start the sqs route .Also post this step we have a couple of routes which further process the messages consumed .

Have any of you faced such issues if yes please help .The load we receive on the queue ranges at around on an average 1000 + messages in a day
