PH31668: MQ Z/OS: THE 'ARCHIVE LOG CANCEL OFFLOAD' COMMAND RECEIVES ABN=30A-00000024 IN CSQJDS04

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Log archiving failed due to a lack of space, eventually
  resulting in CSQJ110E and CSQJ111A messages. After the space
  issue was resolved, the ARCHIVE LOG CANCEL OFFLOAD command was
  issued. Then, the following messages and abend occurred:
  
  CSQ9022I !MQ0M CSQJC001 ' ARCHIVE LOG' NORMAL COMPLETION
  
  CSQJ128E !MQ0M LOG OFFLOAD TASK FAILED FOR ACTIVE LOG

  ABEND 30A:
  Explanation
  An error occurred when the system tried to run an R form of the
  FREEMAIN macro. A reason code in the SDWACRC field of the
  system diagnostic work area (SDWA) explains the error:
  
  Code 24:
    One of the following:
    - In the private area, the area specified on a FREEMAIN is
      larger than the area specified on the original GETMAIN.
    - The FREEMAIN start address is not valid.
  
  
  In the dump, the FREEMAIN PSW is in CSQJDS04+x'D04' (9.0.0 base
  level) in the expansion of FREEPOOL DCB_ADDR(LdsdDcb).
  
  This problem is a timing issue and has not been observed
  frequently.

  Freeing of access buffer pools for archive log opening and
  closing has been altered in recent releases, and this affected
  CSQJDS04 processing for specific circumstances around archiving
  and cancelling archiving in narrow windows of time.
  

Problem conclusion

• The redundant code has been removed to avoid this re-occurring
  again.
