[lwip-users] TCP Out-Of-Order/Retransmission/Connection closed issue

[Axel Lin]

Hi,
I'm using lwIP git tree (47f55b02bf9f889eb38379a68de9d765c163b89a).
Sometimes I found the connection will be reset, and I found a couple
of TCP Out-Of-Order/Retransmission before connection reset.

Many dup-ack e.g. No110, 112, 190, 191, 330,...

Below is the log can be opened by wireshark.

Is there anything wrong in the log? (lwip+pppos)

Thanks.
