Hi

Thanks for the answer. Now we have more than fifty servers (more than
twenty organizations, each with at least two servers), each one with
about the same number of replication agreements, and we are not having
any problems about resource limits. Each server has its own database
in multimaster mode and the databases of the other organizations in
hub mode. We thought there were a limit of four (4) servers per
multimaster replica; the biggest organization will have now 6 servers,
each one with the replica of its database in multimaster mode, so
that's my question.

Anyone has multimaster replicas with such number of servers? Any suggestions?

Regards.
