Error description

  • After applying PTF UK82814 you may receive DFHSM0002
    severe error(code X'030F') abends in module DFHSMGF. This
    happens because DFHICXM may attempt to FREEMAIN an ICE twice
    after a transaction abend. It is possible that the second
    FREEMAIN call could free an active ICE that belongs to a
    different task and make the storage available for reuse.

    After installing the fix for PM70388 it is possible that SM0002
    abends will occur when the started task performs a RETRIEVE and
    then abends.
    
    DFHSM0002 applid   A severe error (code X'030F') has occurred in
    module DFHSMGF .
    
    CICS will typically continue after the abend.
    
    DFHXMAT tests the start_type as an indicator as to whether a
    RETRIEVE has been done. However the contents of the field being
    tested are unreliable, resulting in an unnecessary call to
    DFHICXM, which in turn attempts to freemain an ICE that has
    already been freemained as part of RETRIEVE processing.

Problem conclusion

  • UK82814
    DFHICP has been changed to ensure that the ICE token is cleared
    by a RETRIEVE so that DFHICXM will not attempt a second
    FREEMAIN.
