Thanks !
Looks like the actual socket structure is altered :
sock_str = {s = 0x7f4818da11b8 "udp:172.16.1.115", len = 21}
length is 21, while only 16 chars are printed -> 5 are missing ( ':' + 4
for port) .
What exact opensips revision are you using ? I need to figure out a way
to see where in the code the sock_str is altered.
