Проверял? Проверял. Работает? Работает. Не трогай!
Есть несколько причин почему PHP-FPM достигает максимума в pm.max_children: слишком много паралелльных запросов, слишком медленно выполняются скрипты, или слишком маленькое значение.... увеличте max_children, только следите чтоб у вас памяти хватило на все.
