APAR status

  • Closed as program error.

Error description

  • Update statistics high (fieldname) on a fragmented table
    (statlevel fragment) can use an unexpected huge amount of sort
    memory.
    This only happens when update statistics medium is run before
    update statistics high.
    

Local fix

  • You can use "update statistics low for table tab(field) drop
    distributions only;" to prevent the memory consumption.
