Error description

  • In a DPF environment, work areas associated with JSON processing
    are incorrectly not freed at the end of statement execution on
    remote partitions (i.e. other than coordinator partition).
    Subsequent reuse of cached SQL section copies by other
    applications can result in a wide variety of symptoms (traps,
    memory corruption, errors).
    
    Traps may show the DB2 JSON function sqlriJsonCtorInitWA but
    many/most will not. It should be assumed that any DPF
    environment where json functions are used - incluing but not
    limited to json_to_bson, bson_to_json - will experience various
    and severe symptoms caused by this bug.
