Problem summary

• ****************************************************************
  * USERS AFFECTED: .                                            *
  * All DRF V3.1 Installations.                                  *
  ****************************************************************
  * PROBLEM DESCRIPTION: DRF GETMAINs storage for Log Data Set   *
  * Descriptor (LDSD) blocks and FREEMAINs them when no longer   *
  * needed. In some instances with IMS V10 RESLIB, DRF           *
  * FREEMAINed more storage than was GETMAINed. This eventually  *
  * may lead to a storage overlay resulting in unpredictable     *
  * results including hang, 0C4, A78 or other storage oriented   *
  * abends. The potential for this problem also exists when      *
  * running with IMS V9 RESLIB.                                  *
  ****************************************************************
  * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF      *
  ****************************************************************
  .
  

Problem conclusion

• * DRF now FREEMAINs the correct length and the storage         *
  * overlay is prevented.                                        *
