При 502 такая ошибка
2009/10/12 16:02:30 [error] 18307#0: *161275 recv() failed (104: Connection reset by peer) while reading response header from upstream

Нагрузка небольшая. Bad Gateway возникает примерно раз за 2-4 часа. Пробовал повесить FastCGI на localhost, от проблемы не избавило. Интересно то, что бекенд живет, хотя nginx и возвращает 502. Лечится все перезапуском бекенда.
Посоветуйте где копать.
