Error description

  • When using the DB2 Data Server Driver Package, there might be a
    small memory leak (anywhere from 1-30 bytes) for every
    connection request made with the DB2 .NET data provider.
    
    The problem would only occur if the DS Driver was processing
    keywords from the db2dsdriver.cfg file for the connection.  For
    example keywords like Authentication and ClientApplicationName.
    
    This specific problem would not happen if using ODBC/CLI or OLE
    DB, as the process where a leak was detected is only triggered
    by the DB2 .NET data provider.
    

Local fix

  • Removing the keywords from the db2dsdriver.cfg file may reduce
    or eliminate the leak.   Using an instance based client like the
    Data Server Client would also help eliminate the leak.
