Здравствуйте!
Сервер работает в связке nginx+apache (mod_php).
На сервере предоставляется хостинг поэтому довольно много сайтов - 300-600.
В течении дня возникают ситуации когда копятся большое кол-во
процессов апача, которые естественно провоцируют рост LA иногда сразу
до 20-30.
После перезапуска апача всё встаёт на свои места, но не сильно
надолго. Причём с виду ничего особенного - идут стандартные запросы...
Подскажите пожалуйста, что можно предпринять чтобы предотвратить рост
процессов - возможно ли как-то ограничить нагрузку на CPU, или сделать
настройки в самом апаче от этого? Возможно ли тут влияние настроек
nginx?
Вот типичный список процессов во время перегрузки:
