OA42163: ABEND S073-08 DURING SDUMP PROCESSING

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When a dump ends the RSB DIE is not dequeued. This prevents the
  RSB DIE from being queued for the next dump. This opens a window
  where the RSB DIE for the previous dump can call IAXXP using
  SMWKRSM for its input parameters at the same time that IEAVTSSM
  calls IAXXP using SMWKRSM for the next dump. This causes SMWKRSM
  to be overwritten resulting in S073-08 on return to IEAVTSDB
  from the RSB DIE as the RSM locks have not been freed.
  
  IVP instructions:
  1. Two dumps taken in quick succession
  2. Systrace shows S073-08 at IEAVELK+125E (UA62105)
  3. The TQEVAL for the RSB DIE will be just prior to the time
     of the S073-08 and will be for the previous dump. The RSB
     DIE TQE address is at RTCTDIRS?+10.

  * PROBLEM DESCRIPTION: ABEND073 RSN08 IEAVELK                  *

  * RECOMMENDATION:                                              *
  ****************************************************************
  The problem can occur when multiple SVC dumps, requesting
  disabled summary dumps, are requested one right after the
  other. SDUMP mainline, and an SDUMP disabled interrupt exit,
  may both make requests of RSM services using the same parameter
  area. Depending upon the timing, the parameter area can be
  updated by one requestor, to prevent the other requestor from
  obtaining RSM locks. This will lead to the ABEND073 RSN08 in
  IEAVELK.
  

Problem conclusion

• Processing was introduced to stop the RSB DIE protection by the
  time the SVC dump completes.
