situation
2 tunnels
1 normal - 2nd with unconnected ending
+ ospfd quagge

At start everything works fine - but after ~ 30-60 seconds - the ospf stops working

This is due to the fact that the ospf daemon sends packets from the same socket on different interfaces - and in the tunnel interface everything goes fine - but in the 2nd packets accumulate
And after a certain accumulation - the socket of the demon daemon stops working on sending completely "No buffer space available "

Is it possible to fix this with settings?
