CommandBuilder Cursor Leaks when using Factory Classes *HELP*

 Using the following code I get a ORA-01000: maximum open cursors exceeded.  As can be seen all of the disposable objects are disposed and therefore there shouldn’t be any leaks.

        Using conn As Oracle.DataAccess.Client.OracleConnection = New Oracle.DataAccess.Client.OracleConnection
            conn.ConnectionString = connectionString
            conn.Open()
            For i As Integer = 0 To 1000
                Using cmd As Oracle.DataAccess.Client.OracleCommand = conn.CreateCommand
                    cmd.Connection = conn
                    cmd.CommandText = "SELECT * FROM TESTER WHERE ID = " & i
                    Using da As Oracle.DataAccess.Client.OracleDataAdapter = New Oracle.DataAccess.Client.OracleDataAdapter
                        da.SelectCommand = cmd
                        Using cb As DbCommandBuilder = New Oracle.DataAccess.Client.OracleCommandBuilder
                            cb.DataAdapter = da
