启用crontab后运行程序报错 ERROR php_swoole_server_rshutdown (ERRNO 503)

Empieza reproduciendo el fallo con config/autoload/crontab.php habilitado y la configuración de task_worker y los callbacks mostrados en config/autoload/server.php. Ejecuta el ejemplo de LogCleanerTask e inspecciona el stack a través de vendor/symfony/console/Output/StreamOutput.php:76 y Hyperf\Framework\Logger\StdoutLogger. Se considera terminado cuando la tarea programada puede registrar mensajes sin el error fatal de la coroutine del socket ni una salida anormal del worker.

环境
PHP 7.3.26
swoole 4.6.1
hyperf v2.1.1

配置config\autoload\crontab.php

return [
    // 是否开启定时任务
    'enable' => true,
];

config\autoload\server.php

'settings' => [
        ...
        // Task Worker 数量，根据您的服务器配置而配置适当的数量
        'task_worker_num' => 1,
        // 因为 `Task` 主要处理无法协程化的方法，所以这里推荐设为 `false`，避免协程下出现数据混淆的情况
        'task_enable_coroutine' => false,
    ],
    'callbacks' => [
        ...
        // Task callbacks
        Event::ON_TASK => [Hyperf\Framework\Bootstrap\TaskCallback::class, 'onTask'],
        Event::ON_FINISH => [Hyperf\Framework\Bootstrap\FinishCallback::class, 'onFinish'],
    ],

运行官方文档示例

<?php

declare(strict_types=1);
namespace App\Task;

use Hyperf\Crontab\Annotation\Crontab;
use Hyperf\Di\Annotation\Inject;

/**
 * @Crontab(name="LogCleanerTask", rule="*\/5 * * * * *", callback="execute")
 */
class LogCleanerTask
{
    /**
     * @Inject()
     * @var \Hyperf\Contract\StdoutLoggerInterface
     */
    private $logger;

    public function execute()
    {
        $this->logger->info(date('Y-m-d H:i:s', time()));
    }
}

关闭crontab则不会报这个错误
