Приветствую.
Сегодня нужно было добавить еще один server {...}, и по привычке выполнил не
перезапуск а переконфигурирование (ч-з reload), в ответ получил "ОК", но
сайты "отвалились". 

Вот что в dmesg:

После "сбоя" пришлось немедленно убить nginx (ч-з killall -9) и запустить
заново, потому что при попытке выполнить restart скрипт тупо висел на этапе
"Stopping nginx:......................".
