我向超过3000台设备的多台设备发送推送通知时遇到上述错误。有任何处理它的建议吗？

代码数量在循环中的代码：

//私钥密码（ck.pem文件）

$pass = 'push';

//从http get或命令行

获取参数

        $message = 'Application(s) update available';
        //$badge = (int)$_GET['badge'] or $badge = (int)$argv[2];
        $badge = $count_update;
        //$sound = $_GET['sound'] or $sound = $argv[3];

//构造通知有效载荷

                $body = array();
                $body['aps'] = array('alert' => $message);
                if ($badge)
                    $body['aps']['badge'] = $badge;

                /* End of Configurable Items */

                $payload = json_encode($body);
                $ctx = stream_context_create();
                stream_context_set_option($ctx, 'ssl', 'local_cert', 'ckappmart.pem');

//假设已删除私钥passphase。

                stream_context_set_option($ctx, 'ssl', 'passphrase', $pass);
                $fp = stream_socket_client('ssl://17.172.238.221:2195', $err, $errstr, 60, STREAM_CLIENT_CONNECT, $ctx);

                if (!$fp) {
                    //print "Failed to connect $err $errstrn";
                }
                else {
                    //print "Connection OKn";
                }

                if($num_getNonMdmPushToken!=0) {
                    for($count=0;$count<1;$count++) {
                        $msg = chr(0) . pack("n",32) . pack('H*', str_replace(' ', '', $deviceToken[$count])) . pack("n",strlen($payload)) . $payload;
                        //print "sending message :" . $payload . "n";
                        fwrite($fp, $msg);
                    }
                }
                fclose($fp);
