Я недавно установил memcached для разрешения высокой загрузки ЦП, потому что он продолжал вызывать db для каждого запроса. Теперь, кажется, у меня проблема с памятью.
У меня в общей сложности 24 ГБ оперативной памяти и до сих пор не достаточно. Я только выделил 64MB для memcache, но это выходит за рамки лимита. Любую проверку или исправления я могу сделать?
