[Serusers] More usrloc sync questions

[AJ Grinnell]

So I can get replication working, but I constantly am getting errors
about receiving SERs usrloc not being able to insert into the
database. My guess is because the contact is already there by the
originating SER. I have a MySQL cluster that both SERs are using. My
question is this, how can I save the contact in the SER that is
receiving the contact, without SER trying to write the contact to the
DB?
