Per Mike's suggestion -- he asked to sprinkle with printfs the potential
error returns in net and netinet .
And the culprit is:

int
in_pcbladdr(inp, nam, plocal_sin)
	register struct inpcb *inp;
	struct sockaddr *nam;
	struct sockaddr_in **plocal_sin;
{
	struct in_ifaddr *ia;
	register struct sockaddr_in *sin = (struct sockaddr_in *)nam;

	if (nam->sa_len != sizeof (*sin))
		return (EINVAL);
	if (sin->sin_family != AF_INET)
		return (EAFNOSUPPORT);
	if (sin->sin_port == 0) {
			  printf("in_pcbladdr  \n");
			  printf("addr %x \n", sin->sin_addr.s_addr);
		return (EADDRNOTAVAIL);
	}

The port and address field are 0.

The system call was a sendto with port 29710 and address 127.0.0.1.


	Any clues?
	
	Tnks!
