Мультикаст маршрутизация mrouted

Всем привет.
Есть такая задача:
Надо маршрутизировать мультикаст трафик, который принимается интерфейсом xxx.xxx.xxx на 192.168.0.1. Поставил себе mrouted

/etc/mrouted.conf
tunnel 192.168.0.1 239.0.0.100

запускаю mrouted -c /etc/mrouted.conf -d

[root@nevsky /]# mrouted -c /etc/mrouted.conf -d

вродьбы все как положено, но потом после кучи запросов от машин с сети xxx.xxx.xxx/24 происходит такое:

21:52:45.418 setsockopt MRT_ADD_VIF on vif 2: No buffer space available

В чем дело. Я уже лоб поломал.
