亚马逊sqs抛出异常连接重置

我使用AmazonSQSAsyncClient连接Amazon SQS,但有时我在日志中看到以下执行:

我正在使用AmazonSQSAsyncClient作为单例的应用程序.

代码段如下.

static{
        if(sqsObj == null){
        sqsObj = new AmazonSQSAsyncClient(new ClasspathPropertiesFileCredentialsProvider("app.properties"));
        sqsObj.setRegion(Region.getRegion(Regions.valueOf("sample region"));
    }
}

通过使用sqsobj,我正在执行诸如创建队列,发送消息和接收消息之类的操作.它工作正常,但有时会抛出异常,如上所述.重新启动应用程序后,它可以正常工作.

我正在使用aws-java-sdk-1.7.1.请对此提出建议.
