* PROBLEM DESCRIPTION: ABEND0C4 RC0000003B DSNSVSFB +0698      *
*                      with CP parallelism                     *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
During cleanup processing for CP query parallelism tasks, if
an ABEND occurred within a timing window, a pointer to a freed
control block that represented a parallel task would remain
pointing to freed storage.  This pointer was later referenced,
and caused the symptom ABEND.

    



Problem conclusion


    

  • DB2 code has been modified to correctly zero the pointer noted
above, when its storage was freed.
