Obtain the fix for this APAR.

APAR status

• Closed as program error.

  * RECOMMENDATION:                                              *
  ****************************************************************
  zEDC normal task termination could delete an active Rendezvous
  token (RZVToken) that is active under another task when
  cleaning up the finished task.  This could result in an
  ABEND0C1 when attempting to use the RZVToken that was deleted
  prematurely.
  

Problem conclusion

• zEDC task termination processing has been enhanced to only
  delete RZVTokens that are associated with the task being
  terminated.
