HiI'm using lwIP (2.1.3-RC1) with the httpd web server from the apps directory in my embedded application. After loading a web content from the web server a periodic communication starts from the web browser that opened the website. This all works, but after a view minutes the periodic communication gets broken (the web server/lwIP stack itself does not crash). After a reload of the web site the periodic communication is established again for a view minutes.
In the attached Wireshark capture file I can see many frames (from the web browser) with the set ACK RST flags. For me it not clear why the web browser sends this frames and if it is the reason for the broken periodic communication ? Any help and maybe some explanation would be very welcome.
I also activated the debugging output and the internal lwIP asserts, but this did not help me to track down the problem. The web server does not support encryption.
The lwIP uses FreeRTOS with the sys_arch files found in the contrib package.IPs used in the Wireshark capture : The web server uses 192.168.3.131 and the client (web browser) 192.168.10.103 .
Thank you very much for any help Roland
