OK, this should cure it. BTW, this indicates that your app is retransmitting unnecessarily which might be a problem in itself. This patch applies to all recent 2.6 kernels. [NET]: Set truesize in pskb_copy Since pskb_copy tacks on the non-linear bits from the original skb, it needs to count them in the truesize field of the new skb.
