Cause
This error occurs if collection fast build finds a duplicate key value while building a collection in which duplicates are not allowed.
Action
The duplicate keys are identified with collection and member object identifiers in the reorganization log file. Abort the reorganization, resolve the duplicate keys, and then retry the reorganization. To resolve the duplicate keys:
Change the member object key values.
Add a duplicate resolver key element to the collection keys.
Change the collection to allow duplicates.
