  ****************************************************************
  * RECOMMENDATION:                                              *
  * Apply corrective PTF when available                          *
  ****************************************************************
  REORG INDEX SHRLEVEL CHANGE, without specifying NOSYSUT1 and
  the subsystem parameter REORG_INDEX_NOSYSUT1 not enabled, was
  run on an index containing a small number of keys.  An attempt
  was made to initialize an unneeded pointer from storage that
  was unallocated which resulted in the ABEND0C4 at DSNUREKY
  OFFSET0450.
  For Db2 13 for z/OS, this situation could only occur for
  REORG INDEX SHRLEVEL NONE
  

Problem conclusion

• REORG INDEX code has been changed to fix the aforementioned
  problem.
