  ****************************************************************
  PROBLEM SUMMARY:
  Storage usage grows when collecting statistics for NTH
  and/or when collecting DBM1 storage information via the
  Classic I225 command such as with the R.M.A menu option and
  via TEP situations such as KD5_MVS_Extended_CSA_Warning.
  This causes increased CPU usage.
  
  PROBLEM CONCLUSION:
  Free storage appropriately.
  
  KEYWORDS:
  HIGH CPU MEMORY LEAK NTH STATISTICS DBM1 STORAGE
