This error indicates that some server is confused about what is the current =

transaction or who is the sync site.  In normal operation with correctly=20
configured servers, this should be quite rare and always transient.

If you are able to read back the change, then it made it to at least one=20
server, and the confused server will have been marked out of date and will=20
eventually pick up a new database.  So, there is no long-term ill effect.

However, if you are seeing this on a regular basis, then it seems likely=20
you have some sort of configuration problem.  Make sure all of your=20
dbservers have the _same_ server-side CellServDB, and that it lists each=20
server exactly once.  If the servers have more than one interface, only one =

interface per server should be listed in the server-side CellServDB.
