[keycloak-user] LDAP Federation - synchronization on cluster error

Hello, Has anyone have a problem with synchronization on JBoss cluster? Recently I've noticed that some synchronization ends with error: *javax.persistence.OptimisticLockException: Batch update returned unexpected row count from update [0]; actual row count: 0; expected: 1 * If synchronization is started manually there is no problem with the feature. I think that it can be a problem with scheduled job synchronization on cluster. BasicTimerProvider uses simple, not synchronized java timers and it can cause race condition on database.
