Research direction

Start by reproducing the failure with config/autoload/crontab.php enabled and the task_worker settings and callbacks shown in config/autoload/server.php. Run the LogCleanerTask example and inspect the stack through vendor/symfony/console/Output/StreamOutput.php:76 and Hyperf\Framework\Logger\StdoutLogger. Done means the scheduled task can log without the socket coroutine fatal error or abnormal worker exit.

Description

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()));
    }
}
