PH50190: ABEND 0D7-25 IN JOB THAT EXECUTES MQPUT TO A TOPIC AND ABEND 058-3C OR 058-24 IN QMGR MSTR 22/11/08 PTF PECHANGE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• A task from a job XXX was connected to MSTR and had just done a
  MQPUT to a topic. A MQPUT to a topic requires an execution unit
  switch, so a SRB is scheduled to CSQVEUS2 to call CSQMTPUT to
  do the put. The task of job XXX subsequently paused to wait for
  this request to complete.
  
  Once the SRB had completed the request, it released the paused
  XXX task. The SRB was then un-dispatched due to an external
  interrupt (WTI or EMS). The released XXX task then went on to
  disconnect from the QMGR, which involves doing an ATSET to
  remove PT authority for the allied address space.
  
  When the SRB was re-dispatched, it hit the abend 0D7-25. The
  QMGR termination with 058-3C or 058-24 was initiated due to the
  abend occurring in an unfortunate place in CSQVSRX.
  
  Additionally and unfortunately the SRB is suffering timed
  external interrupts.

  ****************************************************************
  A task issuing a full cross memory Execution Unit Switch to and
  SRB resumed its original caller and then was subsequently
  un-dispatched due to an external interrupt. In this time the
  original task disconnected from MQ and removed the QMGR's
  authority to the application ASID. When the SRB was
  redispatched it attempted to restore its cross memory
  environment with its secondary address space which was set to
  the asid of the orginal task.
  
  This leads to a series of 0D7 & 058 abends and may lead to qmgr
  termination as the PT authority has been removed as part of the
  disconnect from MQ.
  

Problem conclusion

• The code has been corrected so that SRB's that are scheduled
  internally in the MSTR address space have their secondary
  address space set to the asid of the QMGR to avoid attempting
  unnecessary cross memory actions to the disconnected task.
