  *                      it fails to access a message queue      *

  ****************************************************************
  When stopping the Defense Manager Daemon (DMD) while it is not
  defined with a UID(0), DMD will fail to successfully access a
  message queue during cleanup. DMD does not have write access
  to the queue. Stop processing continues to complete.
  When RACF auditing is active the following message is displayed:
  ICH408I USER(DMD     ) GROUP(OMVSGRP ) NAME(NAME SVR)
    00000000 CL(IPCOBJ  ) ID(0000000022)
    INSUFFICIENT AUTHORITY TO MSGSND
    ACCESS INTENT(-W-)  ACCESS ALLOWED(OWNER      ---)

Problem conclusion

• EZADMSMG was modified to create the message queue with read
  write access so that it can be successfully accessed during
  stop processing. EZADMMTH was included for maintenance
  purposes only.
