Please answer these questions before submitting your issue.

  1. What did you do? If possible, provide a simple script for reproducing the error.

I have a small pet project and I added one docker compose service for a Swoole server and another one for the FPM server. The application can be checked here: https://github.com/CViniciusSDias/picpay-challenge/tree/swoole-plus-fpm When running docker compose up -d, everything seems to work fine and I am able to perform requests (http://localhost:8123/users, for example), but if I perform a small stress test, it gives me error responses and shows the following warning in the logs:

app-1 | [2024-04-14 14:04:43 $7.0] WARNING Server::check_worker_exit_status(): worker(pid=19, id=4) abnormal exit, status=0, signal=11 app-1 | A bug occurred in Swoole-v5.1.1, please report it. app-1 | The Swoole developers probably don't know about it, app-1 | and unless you report it, chances are it won't be fixed. app-1 | You can read How to report a bug doc before submitting any bug reports: app-1 | >> https://github.com/swoole/swoole-src/blob/master/.github/ISSUE.md app-1 | Please do not send bug reports in the mailing list or personal letters. app-1 | The issue page is also suitable to submit feature requests. app-1 | app-1 | OS: Linux 5.15.146.1-microsoft-standard-WSL2 #1 SMP Thu Jan 11 04:09:03 UTC 2024 x86_64 app-1 | GCC_VERSION: 12.2.0 app-1 | PHP_VERSION : 8.3.4

This is how I executed the stress test:

docker run --rm -it williamyeh/wrk -c 100 -d 2 -t8 http://host.docker.internal:8123/users
  1. What did you expect to see?

No errors in the logs and a successful test result

  1. What did you see instead?

Only 2 requests being handled by swoole and multiple of the following logs in the output:

I will test it later.

Or try to follow this tutorial to see where the problem lies. https://wiki.swoole.com/en/#/other/issue?id=about-segmentation-fault-core-dump

CViniciusSDias commented 7 months ago

If I don't enable hooks, i.e., if I remove the following lines, I don't get the error:

$_SERVER['APP_RUNTIME_OPTIONS'] = [
    'settings' => [
        'hook_flags' => SWOOLE_HOOK_ALL,
    ],
];
CViniciusSDias commented 7 months ago

Setting it to SWOOLE_HOOK_ALL & ~SWOOLE_HOOK_FILE & ~SWOOLE_HOOK_STDIO also makes the error go away. So the problem seems to be with SWOOLE_HOOK_FILE and / or SWOOLE_HOOK_STDIO. With that, I assume it's a problem that happens when logs are written.
