странная смерть worker-ов.

[Arkadiy Kulev]

Здравствуйте,

я использую nginx для раздачи статики, а в случае если он не находит
файла на диске, он обращается на backend.

стал замечать, что в stub_status стала накапливаться статистика
(большие числа, не совпадающие с действительностью) и мне
порекомендовали проверить на тему умирающих worker-ов.

глянул в error.log, и в правду - nginx у меня сыпется постоянно.

Nginx версии 0.6.32, что делать?
