Usage count = 1". The 6to4 tunnel is over the kernel PPPoE tunnel in case that makes a difference What it's trying to do is /sbin/ip tunnel del tun6to4, which works just fine when run by itself, when looking at /proc/net/dev the device is no longer there at that point. I think the situation where it breaks if the ppp device it's running on top of goes down just before. Just a guess tho :-) Any obvious explanations or should I poke further?
