[SR-Users] MySQL duplicate entry error on location after 5.5 => 5.6 upgrade

Hi list Since updating 5.5 to 5.6 i often see this message in the logs: ERROR: db_mysql [km_dbase.c:122]: db_mysql_submit_query(): driver error on query: Duplicate entry 'uloc-645ca178-f29e-1' for key 'location.ruid_idx' (1062) ERROR: <core> [db_query.c:244]: db_do_insert_cmd(): error while submitting query ERROR: usrloc [ucontact.c:687]: db_insert_ucontact(): inserting contact in db failed ****** (uloc-645ca178-f29e-1) ERROR: usrloc [urecord.c:420]: wb_timer(): inserting contact into database failed (aor: *******) usrloc is dmq synced between two nodes. Were there some changes which could have caused this issue?
