Every time there is 500 error server cpu gets 100% and crashes needs to restart every time

PHP Version 7.4
Laravel Version 8.83
Ubuntu Ngnix

I found this in php7.4-fpm.log error logs

error.log

2022/09/13 10:52:53 [error] 889#889: *3130 upstream timed out (110: Connection timed out) while reading response header from upstream

Your PHP-FPM config is set to the default 5 children (simultaneously executing PHP requests) and that limit is (on occasion it appears) being exceeded and hence the 500 error. Have a read of this article if you want background knowledge on the PHP-FPM max_children setting.

There is also a handy online calculator for calculating a more appropriate max_children value for your server configuration.

Once you have calculated a new (higher) value for the setting, you'll need to update your PHP-FPM configuration and reset the PHP-FPM service on your server for the change to take effect.
