Question

我写了一个php worker从RabbitMQ队列中获取数据。该php worker在某些服务器上作为后台作业成功运行，该服务器连接RabbitMQ服务器以使用AMQP php扩展来消费数据。队列中没有数据入队后在15分钟内，php脚本抛出AMQPException。例外是：

AMQPException对象（

[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

                [args] => Array
                    (
                        [0] => Closure Object
                            (
                                [parameter] => Array
                                    (
                                        [$message] => <required>
                                        [$q] => <required>
                                    )

                            )

                    )

            )

以下是我的工作人员代码：

  <?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"]:"";
    $mail_body_content = isset($data["body"])?"<pre>".$data["body"]."</pre>":"";
    $mailfrom          = isset($data["mailfrom"])?$data["mailfrom"]:"";
    $cc                = isset($data["cc"])?$data["cc"]:"";

    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<$mailfrom> \n".
                        "Cc:$cc\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 :

        started!");
        $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();
