[lwip-users] LWIP stops responding on ping and HTTP calls from a webbrowser |

Dear all
I am using Lwip 1.3.1 & 1.3.2
untill recently I had no problems using the stack.
But now I'am experiencing
something strange. I use a webserver and a telnet module.
After a boot of
the software everything works ok. I can Ping, acces the webserver pages, open
the telnet server.
But at a point the websever and ping stop working. In
wireshark i see my PC sending request to the embedded device
a STM32F217 but
the stack does not send a respons.
After some waiting the ping work
again and the webserver is also reachable. however something for a short period.
I am thingking that some resources on lwip the stack are not cleared
properly and after a timeout period some parts of the stack are
cleaned.
when I stated using Lwip is was able to run ping
and webserver for days without blocking or failing. But somehow this
is compromised.
does anyone have any sugestions or question on how
to find out more about the problem.
I set a breakpoint in the
TCP.c and Tcp_in file where I think the program should proces any
data. in normal operation this breakpoint is serviced however when the
request from the PC is not answered the breakpoint is not
reached.
Thanks ik advance for everyone wo read this and might
have a suggestion.
Ruben
