Well I found the source of my TCP dying on the 3rd page refresh:
tcp_listen()
I had the lwipopts.h set to:
#define TCP_LISTEN_BACKLOG 1
#define TCP_DEFAULT_LISTEN_BACKLOG 5
and the server HTTP.c module was calling "tcp_listen()"
That caused the problem. It was a backlog issue.
I set:
#define TCP_LISTEN_BACKLOG 0
and no problem with multiple page refreshes.
However I then modified the server HTTP.c so it calls
if (TCP_LISTEN_BACKLOG==1)
tcp_listen_with_backlog(pcb,backlog)
else tcp_listen(pcb)
My question is, what is the "backlog" param value suppose to be?
I set it to TCP_DEFAULT_LISTEN_BACKLOG.
So far, if I try to use the backlog function, it doesn't keep working.
It keeps exiting at:
#if TCP_LISTEN_BACKLOG
if (pcb->accepts_pending >= pcb->backlog) {
printf("ERROR! pcb->accepts_pending >= pcb->backlog\n");
return ERR_ABRT;
}
#endif /* TCP_LISTEN_BACKLOG */
in "tcp_listen_input()" in TCP_IN.H.
Is this backlog function not working? Not working in Raw?
What's the story on using this "tcp_listen_with_backlog()"
Thanks, Chris.
