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.
