Details:

Hello, I use lWip from Linux.

Sometimes there is the strange behavior of the socket. 

Following the closure of the socket, he turns state FIN_WAIT_2 but never
switch to TIME_WAIT or CLOSE_WAIT.

Stack infinitely (Observed 15-20 minutes) sends tcp data.

21:23:43.250395 IP 82.18.19.2.3793 > 66.249.89.190.80: . ack 1 win 0

        
Unfortunately, I failed to record the entire session. This behavior occurs
infrequently.

Perhaps a bug occurs because I use self-tuned lwipopts.h.
