Error description

  • You are running with CICS TS 4.2, and receive a dump with
    message: DFHSM0002 A severe error (code X'0D06') has occurred
    in module DFHSMMF.
    .
    Trace entires show that there is trouble FREEing ADPTFLDS,
    because it is not on a 8 byte boundary.  ADPTFLDS is new
    in CICS TS 4.2.
    SM 0D01 SMMF  ENTRY FREEMAIN ADPTFLDS,000000xx,SHARED_CICS
    SM 0D06 SMMF  *EXC* Address_not_on_8_byte_boundary FREEMAIN,
       ADPTFLDS...
    .
    Further investigation indicates that DFHICP is attempting to
    FREEMAIN storage if ICE_ADAPTER_ADDR is non-zero.  This
    setting is for origin data returned by adapters, but
    shouldn't have been gathered in the case at hand because a
    START with TERMID shouldn't request origin data.

    ****************************************************************
    An EXEC CICS START is performed at CICS 4.2.  In the case of a
    local request, after the START has been scheduled DFHICP
    incorrectly performs a FREEMAIN on the storage pointed to by
    ICE_ADAPTER_ADDR as this field has been erroneously overlaid.
    Alternatively for a remote request TCA field TCZICADP contains
    the erroneous overlay.  This results in DFHEIIC performing an
    invalid FREEMAIN.
    In either case the FREEMAIN fails resulting in the X'0D06'
    error.

Problem conclusion

  • Module DFHEIIC has been modified such that, just ahead of the
    call to DFHICP, if ADAPTER_PTR is null, TCA field TCZICADP is
    set to zeros.
    In addition procedure FREEMAIN_ADAPTER_STG in DFHEIIC has been
    modified such that a FREEMAIN only occurs if local field
    ADAPTER_PTR is not null.
