Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Abend S0C4 - 11 when the application issues an MQGET,
  passing in a buffer of around 101,960 bytes but stating that
  the buffer size is actually 3,145,728 (x'300000) bytes.
  When a message larger than 101,960 bytes is retrieved, MQ
  attempts to write into an invalid storage location and an
  S0C4 abend occurs.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of IBM MQ for z/OS Version 9       *
  *                 Release 0 Modification 0.                    *
  ****************************************************************
  * PROBLEM DESCRIPTION: Abend 0C4 occurs in CSQGFRCV after      *
  *                      recovering from an earlier 0C4 in       *
  *                      CSQIMGE9 caused by invalid buffer       *
  *                      parameters on MQGET.                    *
  ****************************************************************
  During MQGET processing, CSQIMGE9 attempts to copy the located
  message into the application buffer provided by the caller of
  MQGET.
  If the application provided invalid buffer parameters (for
  example, an invalid buffer address, or a buffer size larger than
  the size allocated to the buffer), it can be expected that the
  copy will abend 0C4.
  CSQIMGE9 contains recovery to handle such abends, and return
  MQRC_BUFFER_ERROR, however an error in this recovery processing
  resulted in a subsequent unexpected 0C4 in CSQGFRCV.
  

Problem conclusion

• CSQIMGE9 has been changed to correctly handle the expected
  abend 0C4 and return MQRC_BUFFER_ERROR to the application.
