      Description

      Cross-Site replication with multiple site masters may not work properly when configured asynchronously.
      It relies on the deliver order of the updates to the remote site but, with multiple site masters, it is possible an update to go through one of the possible routes. Having commands going through different routes violates the FIFO order needed leading to inconsistent data between sites.
