PHP Ampqlib Consumer死亡:读取数据错误.收到0字节，而不是预期的1字节

好了，这是Symfony2 Commandline脚本的一部分。当脚本正在等待时，它会异常终止。

[PhpAmqpLib'Exception'AMQPRuntimeException]
    Error reading data. Received 0 instead of expected 1 bytes

我搜索了谷歌，发现提到心跳和set_time_out，但是当我试图在构造函数中设置时，而是当我从默认值更改它时，它死得更快。

这就是我的脚本设置。

    // Get the configuration options for RabbitMQ
        $queueConfig = $this->getApplication()->getKernel()->getContainer()->getParameter("rabbit_mq");
    /**
     * Callback function for RabbitMQ
     * Everything in the callback function must remain in the call back function.
     */
    $callback = function($msg)
    {
      $msgObj = json_decode($msg->body, true);
      print_r($msgObj);
    };
    $connection = new AMQPConnection(
        $queueConfig['response']['host'],
        $queueConfig['response']['port'],
        $queueConfig['response']['username'],
        $queueConfig['response']['password'],
        '/'
      );
    $channel = $connection->channel();
    $queueName = 'myQueueName';
    $channel->basic_consume($queueName, '', false, true, false, false, $callback);
    while(count($channel->callbacks)) {
        $channel->wait();
    }

这是来自AMQPStreamConnection.php的构造函数。AMQPConnection扩展了AMQPStreamConnection

public function __construct($host, $port,
                            $user, $password,
                            $vhost="/",$insist=false,
                            $login_method="AMQPLAIN",
                            $login_response=null,
                            $locale="en_US",
                            $connection_timeout = 3,
                            $read_write_timeout = 3,
                            $context = null)

关于如何摆脱错误的想法?
