Symfony 未捕获异常 - '进程已收到信号“9”

Question

我在尝试使用 Phantomjs 和 Symfony 的 Process 和 Reposonse 文件创建 PDF 文档时遇到此错误。

这是我收到的错误信息

致命错误：未捕获异常 'Symfony\Component\Process\Exception\RuntimeException' 消息 'The process has been signaled with signal "9".'

下面是我的代码：控制器文件

    namespace PhantomFox\Capture;

    use PhantomFox\Views\View;
    use Symfony\Component\Process\Process;
    use Symfony\Component\HttpFoundation\Response;

    class Capture
    {   
        protected $view;
        protected $pdf;

        public function __construct()
        {
            $this->view = new View;
        }

        public function load($filename, array $data = [])
        {
            $view = $this->view->load($filename, $data);

            $this->pdf = $this->captureImage($view);
        }

        public function respond($filename)
        {
            $response = new Response(file_get_contents($this->pdf), 200, [
                'Content-Description' => 'File Transfer',
                'Content-Disposition' => 'attachment; filename="' . $filename . '"',
                'Content-Transfer-Encoding' => 'binary',
                'Content-Type' => 'application/pdf',
            ]);

            unlink($this->pdf);

            $response->send();
        }

        protected function captureImage($view)
        {
            $path = $this->writeFile($view);

            $this->phantomProcess($path)->setTimeout(10)->mustRun();

            return $path;
        }
    protected function writeFile($view)
    {
        file_put_contents($path = 'app/tmp/storage/' . md5(uniqid()) . '.pdf' , $view);

        return $path;
    }

    public function phantomProcess($path)
    {
        return new Process('app/bin/phantomjs capture.js ' . $path);
    }

}

这是我的视图文件：

class AppController extends Controller {

    public function index() {

        $this->capture->load('index.html', [
            'order' => '123456',
            'name' => 'Wes Murray',
            'amount' => 100.00,
        ]);

        $this->capture->respond('index.pdf');

    }
}

根据此 post The process has been signaled with signal "9" 这可能与您的主机运行内存不足有关。

This might actually be a ressources problem. You might want to check your server's virtual hardware.

@i.am.michiel , Thanks, virtual server just ran out of memory.

检查您的服务器设置和硬件是否适合您想要的 PDF 操作类型运行。

当您更改 supervisord 配置时也会发生这种情况。

当您更改配置并运行重新读取和更新命令时，supervisord 将向子进程发送停止信号。如果它们没有在 stopwaitsecs 配置变量指定的时间内完成，它们将被 9 个信号杀死。

在我的例子中，我使用的是 Laravel 并且我必须将 stopwaitsecs 值设置为大于我最长的运行ning 作业（正如文档中实际提到的那样）
