            DIA8573C An invalid space map page was found.
  
  The transaction being rolled back must have performed the
  following in this order:
  - updates or deletes that triggered a page merge or page
  deletion in the index and that were performed with exclusive
  access to the table
  - runstats
  - rollback
  
  The table must have 1 or more indexes that were created when the
  table was empty (or that were rebuilt when the table was empty).
  At least one of the indexes must have had less than 25 distinct
  key values for the life of the index.
  

Local fix

• Use db2dart /MI to mark affected indexes bad and have them
  rebuilt upon database restart or first access (based on INDEXREC
  configuration).
