Error: none DB database_node2 state: > 23505 Error: 7 Hi Sai, I would suspect this is due to having another unique index defined on this table in addition to the primary key; there can definitely be issues with this and fairly obscure corner cases when using/writing a conflict handler. That said, you should definitely adjust sequences on both sides of a multi-master sequence so new ids will be staggered. The basic idea being to start one sides’ sequences on evens and the other on odds with INCREMENT2. This is fairly easy to script and there are likely already scripts out there to do this for your entire database. (Don’t have one in front of me, sorry.)
