Re: Worker process exited on signal 11

[Vladimir Shiray <vlad@xxxxxxxx>]

Вот результат на последней сборке 0.5.27
Получил сразу три core одновременно после запуска ab
( в nginx.conf: worker_processes  3; )

По моему субъективному ощущению, ошибка проявляется
после большого перерыва между HTTPs запросами,
обрабатываемыми одним и тем же процессом.
На самом деле  так и происходит, загрузка на HTTPs
ничтожная в сравнений с обычным HTTP.
Сразу после старта  nginx, используя ab, мне не удавалось
ее получить ни разу.
