    Description

      From mongodb/mongo-php-driver#213:

      i use swoole (https://github.com/swoole/swoole-src) , mongodb together, test code like

      <?php
       
      $server = new swoole_server('127.0.0.1', 9501);
      $server->set(array(
          'worker_num' => 1,
          'task_worker_num' => 2,
          'log_file'   => './swoole.log'
      ));
       
      $server->on('workerStart', function($serv, $worker_id){
          echo 'worker start :' . $worker_id . ',pid :' . getmypid() . PHP_EOL;
      });
       
      $server->on('task', function($serv, $task_id, int $from_id, string $data){
          echo 'on task  :' . $task_id . ',pid :' . getmypid() . PHP_EOL;
      });
       
      $server->on('finish', function($serv, $task_id, string $data){
          echo 'on finish  :' . $task_id . ',pid :' . getmypid() . PHP_EOL;
      });
       
      $server->on('receive', function ($serv, $fd, $from_id, $data) {
          $serv->reload(true);
      });
       
      $server->start();
      

      where server receive any data, i will set server to reload, but occurs
