  b-tree node length error
  expected node length <num>, found:  <num>

  Explanation:  The length of each b-tree node is stored after the
  expanded  dbkey  of  the owner record occurrence.  The length in
  the b-tree node and the length computed by examining the entries
  within  the  b-tree  node do not agree.  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.
