Re: Неконтроллируемый объем кеша Nginx

[vlakas]

Роман, Дмитрий, спасибо за рекомендации.

Падение воркеров nginx'а не было замечено. При рестарте nginx воркеры
недолго находятся в состоянии "shutting down". Тут все хорошо.

Сейчас кеш был значительно уменьшен и включен дебаг.

Проблема пока не проявляется, но вижу подозрительные вещи в дебаг логе:
