[lwip-users] netconn_recv returning ERR_CLSD

[Delta Control - Bernd Uttich]

Dear LWIP users,

 

we have netconn_recv returning ERR_CLSD while tcpip_thread

does not return for a long time from:

/* wait for a message, timeouts are processed while waiting */

sys_timeouts_mbox_fetch(&mbox, (void **)&msg);

 

Condition:

Log onto webserver with other browser than IE9 or IE10:

http://213.168.71.43:8012/

 

Username: gast

Password: gast

 

From main_menu.htm click on one channel (1..9).

Now, per second, data is requested and displayed as trend.

 

Now, we use killing Internet Explorer 9 or 10 and request a file.

Absolutely deadly, one which is not present on our server and

gives back a default page:

http://213.168.71.43:8012/ie9test

 

Please, please, please help us here!
