Steps To Reproduce:
From a fresh start, just:
composer require hyperf/signal
php bin/hyperf.php vendor:publish hyperf/signalAt config/autoload/signal.php, uncomment the line:
Hyperf\Signal\Handler\WorkerStopHandler::class => PHP_INT_MINStart the application regurlarly with php bin/hyperf.php start, then try to stop with SIGINT (Ctrl + C).
Hi @leocavalcante ,
This issue may be duplicated to #3150 and #4230. And based on those previous comments, this message seems an expected behaviour in Swoole's deadlock_check config.
Maybe you can disable this check before workers shutting down. In this way it can disable this error message and remain deadlock checks while your application running.
like this:
class WorkerStopHandler extends HyperfWorkerStopHandler
{
public function handle(int $signal): void
{
Coroutine::set([
'enable_deadlock_check' => false,
]);
parent::handle($signal);
}
}Thank you, @albertcht. I'll ignore it as suggested in previous similar issues.
