duplicate hash bucket not found at dbkey <num>:<num>:<num>

  Explanation:  A duplicate hash bucket was expected at the  given
  dbkey,  but  was  not  found.  The pointer to the duplicate hash
  bucket from a primary hash bucket is probably corrupt.

  User Action:  Ascertain if the  index  is  corrupt  by  manually
  verifying  related system records and hash buckets after dumping
  pages of the database.  If the index is corrupt, rebuild it.
