Error description

• You are running CPSM v530 and your CMAS began receiving
  DFHAP0001 messages indicating an 0C4 abend occurred at
  x'FFFFFFFF' in EYU9XLOP:
  .
   DFHAP0001 applid An abend (code 0C4/AKEA) has occurred at
   offset X'FFFFFFFF' in module EYU9XLOP.
  .
  The exception trace for the abending task:
  .
   xxxxx XDF1 XDNR XDNR DAT Excp      5 SETSHORT Ext       CMAS
   xxxxx XDF1      XDNR     Abend       *Abend*            CMAS
  .
  along with the EYUXL0905E messages show the real abend that was
  occurring was an ASRA abend 0C4 in XDF1:
  .
   +EYUXL0905E applid   ASRA IN XDF1, OFFSET 00000A7C PSW=07856000
               A95B9334 LEVEL=JCI700M PFX=EYU
   +EYUXL0905E INTC=0010 ILC=6 TXCP=7F470801 SCODE=S00C4 TRAN=XDNR
               TASK=0037917
   +EYUXL0905E Methods=XDF1,XDNR,XLOP
   +EYUXL0905E BEAR=295B92FC, OFFSET=00000A44
  .
  The abend 0C4 occurred in EYU0XDF1 (base530) at offset x'A7C'.
  The psw is pointing to an MVC instruction:  D203 D4EC E000 in
  routine XDF1_EXIT within the EYUQXMSM CLEAR macro.  It seems
  that access register 14 (AR14) was not cleared correctly as it
  still contained an ALET address.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of CPSM V5.2.                      *
  ****************************************************************
  * PROBLEM DESCRIPTION: Module EYU0XDF1 ABENDs 0C4 when a       *
  *                      SETSHORT exception condition is         *
  *                      raised and fails to return the          *
  *                      correct RESPONSE and REASON codes to    *
  *                      the CPSM API.                           *
  ****************************************************************
  * RECOMMENDATION: After applying the PTF that resolves this    *
  *                 APAR, all CMASes must be restarted.  Note    *
  *                 that the restarts do not need to be occur    *
  *                 at the same time.                            *
  ****************************************************************
  When a CPSM API program performs an EXEC CPSM CONNECT command,
  it acquires an API processing thread which identifies its
  connection to the CMAS and there are 8192 API processing
  threads available on the system.  Once the pool of available
  API processing threads has been exhausted, further attempts to
  perform an EXEC CPSM CONNECT should result in a RESPONSE of
  ENVIRONERROR and a REASON of SOCRESOURCE.
  During the error handling routine in module EYU0XDF1, the
  access register which had been used to point to the ALET of
  the free thread queue, had not been cleared resulting in an
  0C4 ABEND upon EYU0XDF1's exit routine.  Additionally, during
  the exit routine's processing the API RESPONSE and REASON codes
  would be overridden with a response of FAILED and a reason of
  EXCEPTION.
  

Problem conclusion

• Module EYU0XDF1 has been modified to clear access register 14
  on entry to the error routine which handles the failure to
  acquire a new API thread.
  The code in the module's exit routine which had erroneously
  overridden the API RESPONSE and REASON codes has been
  modified such that the correct API RESPONSE and REASON code
  are returned to the CPSM API program.
