APAR status

• Closed as program error.

Problem summary

• ****************************************************************
  * USERS AFFECTED:                                              *
  * TPC 5.2.x customers using complex SVC subsystems, with over  *
  * 10,000 data path instances.                                  *
  ****************************************************************
  * PROBLEM DESCRIPTION:                                         *
  * When running a probe on a SVC, during the post process the   *
  * memory gets very high, ofter resulting in out of memory      *
  * errors or slow TPC performance because device server does    *
  * not have enough memory to run correct.                       *
  ****************************************************************
  * RECOMMENDATION:                                              *
  * Apply fix maintenance when available.                        *
