    * PROBLEM DESCRIPTION: Message DFHSM0002 code x'0D08' issued   *
    *                      after CWBA transaction is purged.       *

    ****************************************************************
    An EXEC CICS WEB SEND command is issued on a CICS region that
    is under stress ( short on storage ). This causes the task to
    suspend on a DFHSMGF(GETMAIN) request for 'httpout' storage.
    The CWBA transaction is then purged which causes the GETMAIN
    to be purged also.
    Although an error response is returned from DFHSMGF it is not
    checked. As a result, the pointer used for the HTTP response
    gets left with a storage address that has just been freed and
    is still unallocated. During tidyup processing an attempt to
    FREEMAIN the unallocated storage fails and message DFHSM0002
    code x'0D08' is issued. This may be followed by message
    DFHSM0102 A storage violation (code X'0F0C') has been detected.

Problem conclusion

  • DFHWBBLI has been changed to check the response from the
    DFHSMGF(GETMAIN) request for 'httpout' storage. Abend AEXY
    will be issued for response code smgf_purged and abend AEXZ
    for all other error response codes.
