ready needed for duplicate B-tree node at <num>:<num>:<num>

  Explanation:  An attempt to ready the logical area corresponding
  to  a duplicate B-tree index node failed.  This could be because
  of an invalid logical area in a dbkey in the index.

  User Action:  Check  if  there  are  conflicting  users  of  the
  database.  If so, verify this portion of the database when there
  are no conflicting users.  Rebuild the index if it is corrupt.
