[SR-Users] ACK and BYE messages uses wrong socket.

Forgot to mention, i used such a configuration at Kamailio 3.1.5.
As i understood you have got this error on linux-HA slave server ?
For that purpose i used:
*|echo 1> /proc/sys/net/ipv4/ip_nonlocal_bind
|*|*
*|
It's not safe option in general. When ip_nonlocal_bind is enabled linux
kernel allows you to call bind() for the interfaces you don't have and
you can miss a configuration error.
But i think if you know what you are doing it quite safe.
