Доброго времени суток, столкнулись с такой проблемой, раз в четыре часа реконнектится паблишер (Wirecast), им мы пушим на nginx/rtmp, затем с Nginxa ffmpeg демюксит rtmp в mpeg-ts.
Как можно избавиться от этих реконнектов?

Nginx config:

}


application tepmani {

}

application bannampe {

}


}

Wirecast и nginx находятся на одном хосте, пушим по адресу rtmp://localhost/tv/sop, ffmpeg забирает rtmp поток и находится на другом хосте.
Насколько я понимаю, причина реконнектов Wirecast`a в этом "INetStream queueLength over max = 5038".
Как можно, и можно ли вообще увеличить этот queueLength?

Заранее спасибо.
