Dear
The system is compose by:
1. Web server running on STM32 microncontroller with httpd server and lwip 1.4.1.
2. Web client Chrome.
I note with the lwip 1.4.1 stack the tcp_alloc call the tcp_kill_prio and there is a active pcb to be killed.
This lead to call the abort/abandon routine and so send a RST ACK to the client (because the pcb appear to be in established state).
Stange think: with the stack 1.3.2 this never appear (e.g. the tcp_kill_prio function never kill the oldest active connection that has lower priority than prio).
From 1.3.2 to 1.4.1 I have port (as it) the lwipopts.h config file.
did anyone have the same problem?
Any idea or solution?
regards.
