  b-tree node dbkey contains an invalid page number
  expected <num> through <num>, found:  <num>

  Explanation:  Each entry in a b-tree node contains a  compressed
  key  followed  by  a  compressed  dbkey.  The page number of the
  dbkey of the current entry of the b-tree node is not within  the
  range  of  page  numbers for the storage area to which the dbkey
  points.  The valid range is expected  to  be  1  through  <num>.
  Further  verification  of the b-tree is abandoned.  This message
  is followed by one or two lines.  The first line  indicates  the
  parent node of the node in error (unless the parent is the owner
  record occurrence).  A second line indicates  the  owner  record
  occurrence of the invalid b-tree.

  User Action:  Correct the error with the RMU Restore command  or
  the SQL IMPORT statement and verify the database again.
