I'm using network namespaces quite extensively - OpenVPN and IPv6 included - and i haven't hit this bug. That makes it rather likely it depends on some option difference. btw, while the bridging bug is unrelated, it might be the same kind of origin - a skb not being free'd. can you leave the namespace running for a few minutes and check whether the usage count number is higher then? -David
