When worker is enabled then backend becomes slow or unresponsive after certain load. But after disabling worker mode everything is working fine. Whats wrong with this setup? And what is correct setup with laravel, docker and frankenphp (woker mode)?

Build Type

Docker (Debian Bookworm)

Worker Mode

Yes

Operating System

GNU/Linux

Relevant log output

Reproduce the report from the supplied Dockerfile, php.ini, public/frankenphp-worker.php, and Docker Compose configuration, using the Laravel Octane FrankenPHP worker entry point. Start by isolating the worker-mode behavior under load and collecting relevant logs, since the issue provides no log output. Done means identifying the configuration or runtime cause and documenting a verified working Laravel, Docker, and FrankenPHP worker setup.
