Hi
I have to manage a very busy socket in a client connection

I detect disconnection by testing the return value of the send() function 
int size_written = send( fd, .... , ....);
then i test the errno variable
	if (errno == ECONNRESET || errno == EPIPE)
	{
		fd = CODE_SOCKET_CLOSE;
		return CODE_DECONNEXION;
	}

The socket is used both in a thread for reading and 2 timers for writing

It work but when the socket trafic is increased and a server deconnection occured, for an unknown reason the the process
 is stopped. There is no error and no core dump. It's like an exit function call

 Thank for your answer
