-657 FFFFFD6F   SCHEMA SYNC IN PROGRESS

Source:  eDirectory or NDS

Explanation:  An attempt was made to perform a schema synchronization with a server whose schema is in a new epoch state.

Possible Cause:  When a NetWare server using ds.nlm v5.95 or later begins receiving a new epoch on the schema, its schema is locked to prevent other servers from synchronizing any schema information until after the epoch has completed.

Action:  Continuous occurrence of this error should be handled as a schema synchronization failure.
