Nginx, uwsgi и django — upstream timed out на get/post запросы

Приложение работает нормально (проверял на обычном runserver), но есть проблема с настройкой связки nginx + uwsgi
Конфигурация:

* nginx 1.4.2
* python 2.7.3
* django 1.5.4
* uwsgi 1.9
* OS — debian

Конфигурация uwsgi yaml:
 uwsgi:
      chdir: /var/projects/HOA_desk
      module: HOA_desk.wsgi:application
      env: DJANGO_SETTINGS_MODULE=HOA_desk.settings

uwsgi запускаю с помощью: uwsgi --uid 33 --gid 33 -y %config_file%
Nginx: nginx -c /etc/nginx/nginx.conf

А вот и логи…

Когда пытаюсь достучаться до / в логах nginx:

В логе uwsgi — кроме информации после запуска нет ничего.
Я пытался менять сокет-файл на обычный сокет — все тоже саможе. Где я ошибся в маппинге сокета uwsgi < — nginx? Или же не так настроил nginx?

В общем проблема была в том, что nginx собрался на старом ядре (2010 год..) и без поддержки accept4 как и написано в логах.
Обновил ядро, пересобрал — все заработало.
