  ABEND0C4 RC00000004 in DSNIBNRF at offset 1C6C/1C68/1CB4/1CB0
  occurred as a result of a memory overlay caused by a logic
  error when validating an XML document that is bigger than 128K
  using the DSN_XMLVALIDATE user-defined function.
  
  Below is an example query which may cause an abend when
  the input XML document, first parameter to DSN_XMLVALIDATE,
  is bigger than 128K.
  
  SELECT 1 FROM (
    SELECT XMLPARSE(DOCUMENT SYSFUN.DSN_XMLVALIDATE(
    CAST(? AS BLOB(1M)),
    CAST(? AS VARCHAR(20)))) FROM SYSIBM.SYSDUMMYU ) XMLOK;
  

Problem conclusion

• DB2 code has been fixed to prevent the memory overlay caused by
  validating the XML document that is bigger than 128K.
