APAR status

  • Closed as program error.

Error description

  • Whenever you drop an SQL stored procedure or compiled SQL
    function, some memory in the application heap is not freed.
    The amount of memory leaked varies directly with the number of
    parameters in the routine being dropped.  You may use the
    command
    
    db2mtrk -i -d -a
    
    to monitor the size of the application heap (apph).
