A summary of what I posted below .  I have several subordinate databases and each subordinate database acquires there data via a refreshOnly syncrepl.  Instead of storing the contextCSN on the subordinate database the contextCSN gets stored on the superior database.  As a result the superior databases contextCSN is the maximum of the subordinate databases.  This causes all but the syncprov server with the latest contextCSN to abort the sync with "consumer state is newer than provider!"

It seems a configuration option needs to be added that allows storing and reading of the contextCSN on the subordinate databases as well as the maximum contextCSN on the superior database.

The above is my configuration for Chicago.  I have similar ones for New York (ny01) and Los Angeles (la01)
On my global server I am trying to use sync replication to clone each site.  The global server is configured (striped down) as:

Now that I have the configuration out of the way.  Syncrepl on the global server is failing on chi01.  The chi01 server syslog has

So after all that.  Is the syncrepl from chi01 using the contextCSN from the root of the glued database?  It seems all the syncrepl from all the sites fail unless they have the latest change.  How do you handle syncrepl on glued databases?
