PI08244: CSQX053E SNAP DUMP TAKEN WITH FAIGETNEXT QUEUE SYSTEM.BROKER.ADMIN.STREAM IN MESSAGE EXIT

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The FFST was taken by faiGetNext after it received return code
  MQRC_CONNECTION_QUIESCING when calling lpiSpiGet.
  The dump shows that this was returned because the channel
  initiator was shutting down.
  faiGetNext should be able to handle this return code.

  * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 7 *

  ****************************************************************
  * PROBLEM DESCRIPTION: An FFST, indicated by the CSQX053E      *
  *                      message, is produced by faiGetNext or   *
  *                      fmiGetNext during CHINIT termination.   *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The thread processing the SYSTEM.BROKER.ADMIN.STREAM queue calls
  function faiGetNext in order to OPEN the queue and then to GET
  from it, however if the queue manager or CHINIT is terminating
  then a reason code of MQRC_CONNECTION_QUIESCING (2202) may be
  returned which is not handled and an FFST is issued.
  Similarly another thread, processing the
  SYSTEM.BROKER.INTER.BROKER.COMMUNICATIONS queue, calls
  fmiGetNext in order the OPEN and GET from the queue, and again
  the condition above is not handled, resulting in an FFST.
  

Problem conclusion

• faiGetNext and fmiGetNext will now handle the reason code
  MQRC_CONNECTION_QUIESCING in the same way as
  MQRC_Q_MGR_QUIESCING and MQRC_Q_MGR_STOPPING, so that no
  FFST is produced.
