SSI 502 при POST

[Sergey Bondari <bondari@xxxxxxxxxxx>]

Hello nginx-ru,

      Не могу решить одну проблему. По-моему баг в SSI.
      Когда на основную страницу приходит POST больше 10 килобайт, все
      SSI вылетают по 502. Вот выписка из дебаглога. Кто-то похоже
      сделал что-то плохое с файл дескриптором.
      nginx/0.6.32 под Linux Gentoo.
