bird 1.3.1 protocol radv issue

[Bogdan Besliu]

Hello,
I'm testing bird 1.3.1 protocol radv .
The configuration is:
router-id 1.1.1.1;
protocol device {
        scan time 10;
};
protocol radv {
        interface "ppp*"
        prefix 2001:1111:1111::/64 {
          autonomous on;
 };
};

most of the time it works ok but from time to time it happens something like
this:
un 17 18:19:41 ppp-test pppd[8032]: No response to 3 echo-requests
Jun 17 18:19:41 ppp-test pppd[8032]: Serial link appears to be
disconnected.
Jun 17 18:19:41 ppp-test pppd[8032]: Connect time 436.5 minutes.
Jun 17 18:19:41 ppp-test pppd[8032]: Sent 1307925176 bytes,
received 252750 bytes.
Jun 17 18:19:41 ppp-test bird6: radv1: Socket error: Network is
unreachable
Jun 17 18:19:41 ppp-test bird6: radv1: Socket error: Network is
unreachable
Jun 17 18:19:41 ppp-test bird6: radv1: Socket error: Network is
unreachable
Jun 17 18:19:41 ppp-test bird6: radv1: Socket error: Network is
unreachable
...........

and the last messages repeats itself until hdd is full; or bird6 daemon stop
working.
it looks like the problems appear when radv tries to send RA and at the same
time ppp interface goes down.

any ideas ?

thx,

Bogdan Besliu
