Today i come across with the following ORA-00600 error on our DEVELOPMENT instance.

As we all knows ORA-00600 = Oracle BUG

but lets find out more about this particular error

  A mismatch has been detected between Redo records and rollback (Undo) 
  records.

  We are validating the Undo record number relating to the change being 
  applied against the maximum undo record number recorded in the undo block.

  This error is reported when the validation fails.

  This error may indicate a rollback segment corruption.

  This may require a recovery from a database backup depending on 
  the situation.

  If the Known Issues section below does not help in terms of identifying
