Regarding the issue between the number of php-fpm processes and the number of instantaneous dynamic requests

Question

There are 100 php-fpm processes on the machine, and 101 dynamic requests arrive at the same time. Should PHP wait for php-fpm to become free, or directly report a 502 error?

I prefer to report 502 errors directly.
If you are waiting for php-fpm to be idle, what is its logic?

The answer was found 502

Answer 1

The answer is 502
