bird 2.17 on NetBSD and directly connected networks

[Mark Davies]

I've just replaced an archlinux system running 2.14 with a NetBSD system 
running 2.17.

Everything seems to be working fine except that every 20 seconds it 
complains:

   KRT: Error sending route XX.XX.XX.XX/XX to kernel: File exists

for each directly connected network.

ie it tries to write the directly connected network entries out to the 
kernel routing socket and gets told they already exist.

Whats going wrong here?  Should it have determined that they are 
directly connected and not try to write them out or is it expecting the 
write shouldn't fail or what?

cheers
