Hi Sammy,

The registration records are usually bound to an interface (the ip and port the registration was received) - that interface will be used all the time in the communication with the registered end point.

Now, when if server A receives the Registration on interface X, and this is replicated to server B, this server B may not have the X interface, but something else (an Y interface). So the registration record will loose some information (the interface it is bound to). This is the nature of the error message you see.
And yes, using the ip_nonlocal_bind options is the way to go.

Once replicated, the registration records are independent and they do not depend on the what is happening with the original node (where the registration was pushed from).

Hi,
I've a cluster setup with userloc replication enabled for 3+ servers. As soon as a user register anywhere the other servers which receive this replicated contact display these errors:

ERROR:usrloc:receive_ucontact_insert: non-local socket <udp:1X.2XX.XX.XX:5060> ERROR:usrloc:receive_ucontact_insert: failed to process replication event. dom: 'location', aor: '[email protected]'
ERROR:usrloc:receive_binary_packet: failed to process a binary packet!

The solution(kind of) for the same error has been discussed in this thread:
http://lists.opensips.org/pipermail/users/2015-February/030910.html

The question here is, is setting /ip_nonlocal_bind /for this userlocation replication a solution ? or should the replication mechanism be modified to process the replications from other nodes !

Say even if this works, the next question is, what would happen to the contacts from a server which is no longer active. The Contacts disappear as soon as the clusterer node becomes inactive ?

Looking for some clarity on this topic.

Regards,
Sammy
