      If async cross-site replication is used, set max_site_master=1 in RELAY2.
      It can be found in JGroups configuration and max_site_master=1 is the default value.

      If async cross-site replication is used, set max_site_master=1 in RELAY2. It can be found in JGroups configuration and max_site_master=1 is the default value.

      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.
