Hello all, 

I am using LWIP 1.3.1 version which is ported on my board. I have a web page
in my flash which is more then 40KByte. I have connected the board with the
PC using Cross cable to access the webpage from board continously. But
inbetween PC stop accessing the web page from board. I have captured the
transaction between PC and my board using Ethereal. When I go through the
capturing details, PC sends TCP window update request to my board. And after
some transaction I am getting "TCP DUP ACK" and transaction stops. 

I have attached the ethereal trace for the reference. 

I have tried with LWIP 1.3.2 also. I have seen the same problem.

Pls help to resolve this.    http://old.nabble.com/file/p30297629/capture1
