Hi all,

I have a question about when the TCP is closed accidentally, e.g. hit the max retransmission, so the TCP/IP will close, but the socket seems to remain unchanged.

So which layer is responsible of freeing this "dead" socket? Application layer? Or LWIP's socket layer can do it somehow?

Best regards,
