[Users] Socket Errors

Bogdan,

You are right it is the destination. I added the following to udp_server.c
when the error occurs:

            LOG(L_ERR, "sa = %d, %s, %d\n", to->sin.sin_family,
                inet_ntoa(to->sin.sin_addr), ntohs(to->sin.sin_port));

Which logs:

            sa = 2, 0.0.1.244, 5060

This address is clearly invalid. Interesting thing though is that I ran an
ngrep to see if I could locate a message that contains this IP and could not
find one:

ngrep -p port 5060 | grep "0.0.1.244"

The above came up clean even though the log kept reporting the error.

Any more ideas?

Martin
