no memory при постановке на comet-канал

[johnbat26 на gmail.com]

Привет всем.
Мы используем comet модуль: nginx_http_push_module-0.692
До определенного момента все идет хорошо.
Потом начинает валиться ошибка:

Что и где надо подкрутить чтобы памяти хватало?
При постановке на канал, возвращается ошибка 500.
Весь остальной функционал работает нормально.
