…error: [ERROR] WSREP: FSM: no such a transition REPLICATING -> COMMITTED Problem was that transacton was BF-aborted after certification succeeded and transaction tried to rollback and during rollback binlog stmt cache containing sequence value reservations was written into binlog. Transaction must replay because certification succeeded but transaction must not be written into binlog yet, it will be done during commit after the replay. Fix is to skip binlog write if transaction must replay and in replay we need to reset binlog stmt cache.

Problem was that transacton was BF-aborted after certification succeeded and transaction tried to rollback and during rollback binlog stmt cache containing sequence value reservations was written into binlog.
Transaction must replay because certification succeeded but transaction must not be written into binlog yet, it will be done during commit after the replay.
Fix is to skip binlog write if transaction must replay and in replay we need to reset binlog stmt cache.
