Arithmetic operation resulted in an overflow

[verosb]

Hola a tod@s!

Al intentar eliminar los datos de un fichero en AS400 vía conexión ODBC obtengo el siguiente error:

Arithmetic operation resulted in an overflow

Alguien sabe a qué puede deberse???

Dim ConnString As String = "Dsn=XX;uid=XXX;pwd=XXXX"
Dim myConnection As New OdbcConnection(ConnString)
Dim myStoredProc As String = "CALL BAPLICA.CLM_011()"
Dim myCommand As New OdbcCommand(myStoredProc, myConnection)
myCommand.CommandType() = CommandType.StoredProcedure
myConnection.Open()
myCommand.ExecuteNonQuery()
myConnection.Close()
