  The IPIGVQMD routine manages dictionary storage and indices
  used by the IMSPA Statistics report processor (IPIPSTAT)
  using a number of fixed subpools dedicated to individual
  queues. After IMS PA finishes reporting at EOF these indices
  may be released individually or by subpool. In this instance
  there are two error conditions which result in the S0C4 abend
  when the VQMD routine attempts to access a top-level Index.
  Index entry when reporting restarts:
   1. When EOF is signalled to the IMS PA Statistics report
      processor it frees all current dictionary storage but due
      to an incorrect flag setting several dictionary queues
      may be omitted.
   2. The Management Exception report incorrectly uses storage
      from a subpool(93) that is also used by the dictionary
      queues above, when this report finishes processing at EOF
      it release all storage from the specified subpool,
      including the dictionary queues above.
   3. In the above situation, when IMS PA is producing reports
      at intervals rather than at EOJ, then an attempt by the
      VQMD routine to use Index pointers retained in its
      internal tables, but actually released by the MGRX
      routine, will result in S0C4 abend.
  

Problem conclusion

• Resolution is to isolate storage subpools used by the VQMD
  and MGRX outines and to correctly release dictionary entries
  after reporting in the Statistics report processor.
