Php worker 空闲时间 15 分钟后出现异常

Question

我已经编写了一个 php worker 来从 RabbitMQ 获取数据 queue.The php worker 运行成功地作为连接 RabbitMQ 服务器的某些服务器上的后台作业使用 AMQP 使用数据 php extension.After 15 分钟内队列中没有数据，php 脚本抛出 AMQPException。例外是：

AMQPException Object (

[message:protected] => Library error: a socket error occurred
[string:Exception:private] => 
[code:protected] => 0
[file:protected] => /home/indiamart/public_html/dev-weberp-auto-dialer/merp/devworker.php
[line:protected] => 104
[trace:Exception:private] => Array
    (
        [0] => Array
            (
                [file] => /home/indiamart/public_html/dev-weberp-auto-dialer/merp/devworker.php
                [line] => 104
                [function] => consume
                [class] => AMQPQueue
                [type] => ->
                [args] => Array
                    (
                        [0] => Closure Object
                            (
                                [parameter] => Array
                                    (
                                        [$message] => <required>
                                        [$q] => <required>
                                    )

                            )

                    )

            )

    )

[previous:Exception:private] =>

)

下面是我的工人代码：

  <?php
    $callback_func     = function(AMQPEnvelope $message, AMQPQueue $q){
    $data              = json_decode($message->getBody(), true);
    $getDeliveryTag    = $message->getDeliveryTag();
    $ack               = $q->ack($getDeliveryTag);//used $getDeliveryTag


    $to                = isset($data["to"])?$data["to"]:"";
    $subjectMail       = isset($data["subject"])?$data["subject"]:"";

    if(!$ack){//if ack not recieved
        $ack_msg = "Unique id: $uniqueid Subject : $subjectMail";
        @mail("abc@example.com","History Queue Not acknowledged!",$ack_msg);
    }
    if($message->isRedelivery()){
        $red_msg = "Unique id: $uniqueid Subject : $subjectMail";
        @mail("abc@example.com","History Queue Redilivery!",$red_msg);
    }



    $m_headers_trail =  "From:$mailfromname<$mailfrom> \n".

                        "MIME-Version: 1.0 \n".
                        "Content-type: text/html; charset=UTF-8";

    $flag = @mail($to,$subjectMail,$mail_body_content,$m_headers_trail);
    $flag_message = $flag ? "success unique id: $uniqueid Subject :$subjectMail" : "mail failed";

    @mail("abc@example.com","History Mailer Result",$flag_message);

 };


  $host     = "127.0.0.1";
  $vhost    = "/";
  $port     = 5672;
  $login    = "admin";
  $password = "admin"; 


  CHANNEL :

        $cnn = new AMQPConnection(array("host" => $host,"vhost" => $vhost,"port" 
        => $port,"login" => $login,"password" => $password));
        $cnn->connect();
        if(!$cnn){
            @mail("abc@example.com","History Queue Connection

        }
        $ch    = new AMQPChannel($cnn);
        $queue = new AMQPQueue($ch);

        $queue->setName('STS_UPDATE_MAIL');
        $queue->setFlags(AMQP_NOPARAM);

        $queue->consume($callback_func);


        $ch->close();
        $cnn->close();
    }catch(Exception $e){

        if ($ch->isConnected()) {
            $ch->close();
            @mail("abc@example.com","History Queue Closing 
            Connection!","Closed!"); 
        } 
        if ($cnn->isConnected()) {
