I don't suppose you could quickly try this patch it now uses skb_share_check to ensure skb->users == 1 and then I've put back in the skb_clone code that I took out which I think is causing the problem: Tried this one and did not see any errors so far. I will leave my test to run for the night. Please send a v4 and I will try to review it tomorrow. Cheers, Jukka
