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 of sort address spaces is increased and the number of striped sorts in a sort address space is decreased. This could be used as a work-around.
