Source: eDirectory or NDS
Explanation: The eDirectory or NDS replica synchronization process tried to start synchronizing with the target server. However, another eDirectory or NDS server has already begun the replica synchronization process with the target server.
Possible Cause: A server can only receive inbound eDirectory or NDS replica synchronization from one server at a time. When two servers in the same replica ring try to synchronize to the eDirectory or NDS server before one of them completes the synchronization, this error occurs.
Action: Consider this error transitory. The eDirectory or NDS replica synchronization process will resolve the error.
