PH61238: Abend AZI4/AZI6 then EYUO then ACRJ abend then PG0001 abend then possibly SM0002 abends.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Module DFHEIIC's recovery routine EIICREC will sometimes call
  the CPSM routing program EYU9XLOP with an invalid DFHDYE
  commarea. The invalid commarea is close in storage to the
  TASK_ENTRY / TASENTRY / TASN commarea.
  .
  EYU9XLOP sees the invalid DFHDYE COMMAREA and issues an ABEND
  EYUO. That percolates into an ABEND ACRJ. DFHEIIC should
  always address the DFHDYE COMMAREA correctly.

  ****************************************************************
  A CICS transaction is dynamically routed from a TOR to be run on
  an AOR. However, the AOR becomes unresponsive and causes
  transactions to abend with either AZI4 or AZI6.
  
  While recovering from the abend, module DFHEIIC's recovery
  routine sometimes calls the CPSM routing program EYU9XLOP with
  an invalid routing COMMAREA. This invalid COMMAREA is close in
  storage to the TASK_ENTRY / TASENTRY / TASN control block.
  
  EYU9XLOP sees the invalid routing COMMAREA and issues an ABEND
  EYUO. That percolates into an ABEND ACRJ.
  
  The field TAS_XM_TRANSACTION_TOKEN in a TASK_ENTRY control
  block is corrupted. This leads to SM0002 abends with trace
  entries such as:
  SM 0D18 SMMF  *EXC* No_transaction_environment_for_freemain
  SM 0313 SMGF  *EXC* No_transaction_environment_for_getmain
  
  
  Additional keywords: PG0001, SM0002
  

Problem conclusion

• CICS has been changed to pass a valid routing COMMAREA, and
  prevent corruption of TASK_ENTRY control blocks.
