Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When 128 or more striped sorts are started in a sort address
  space, a duplicate DD name is assigned for SORTOUT data set
  erroneously.  This causes the following errors:
   - DUPLICATE KEY ENCOUNTERED
   - IIUB051E REASON=746 (INDEX DATA SET ALLOCATION FAILURE)
   - ABEND0C4 in IIUDMRGR
  

Local fix

• When MAXTASKS xx (xx is larger than 6) is specified, the number

  sorts in a sort address space is decreased.  This could be used
  as a work-around.
