Hi again,
I found that the reason for tcp networking to break is that there are no
available semaphores to initialize. We run out of semaphores, because some
connection don't close. They don't close because they are stuck in read
function.
while(1) {
n = read(s, ...)
if(n<=0) break;
}

Hi Simon,
I return to this old post. As you requested, I migrated our system to 2.0.2

and I observe the same behaviour that I reported above.
I am able to reproduce the break with SOCKETS_D

Two things that I think are worth noting:
a) 1.4.0 is really old. There have been numerous fixes since that. Can

b) 1.4.0 does not co
Hi,
we run lwip-1.4.0 on PPC440 and experience rare random hanging of TCP. I
was able to create a minimal working example to reproduce the hang: Setup a

int socketId = socket(AF_INET, SOCK_STREAM, 0);
if(socketId == -1){...return;}
struct sockaddr_in server;
