  Cause:
  
  
  Index Maintenance: The error often arises when an index is being processed in bulk, and the system has flagged it for mass processing due to certain conditions, such as:
  
  The index is currently being rebuilt or reorganized.
  There are ongoing operations that affect the index, such as data updates or deletions.
  The index is locked or in a state that prevents further processing.
  
  
  
  Data Consistency Issues: If there are inconsistencies in the data or if the index is not properly maintained, the system may mark it for mass processing to ensure data integrity.
