I am running mezzio swoole application in production in aws. Recently my local installation of the production version which was served on localhost:9501 started not to respond (no change made to the code, except composer update). It is running in a docker container with php8.0. With infininte loading of the url localhost:9501, I noticed that the cpu usage of the container is above 200%. Now I have pinned down the area of cpu usage as the moment when mezzio:swoole:start is called. Is there any possibility for this unexpected behavior.
The docker file that creates the container is as follows:

Here start_mezzio shell script is used to start the mezzio swoole server and reload.sh just reloads the container with mezzio:swoole:reload. And this container is now in production without any issues. On my system, localhost:9501 keeps on loading without any response and cpu usage is above 200%. Requesting your kind support.
