Bug #61807 Fatal error encountered during data read

Description:
Hi,
I am working on an application in which I need to read all records from a mySql table and process them one-by-one. Unfortunately I have some 850 records and it takes almost 20 minutes to process and print all the records. But after reading almost a 100 records from DB and printing them I get an exception with Error Message: "Fatal error encountered during data read."
Here are the Exception Details:

MySql.Data.MySqlClient.MySqlException was unhandled

How to repeat:
C# code:

string MyConString = "SERVER=localhost;" +
                "DATABASE=askari9;" +
                "UID=root;" +
                "PASSWORD=;" +
                "Connect Timeout=21600;";
            MySqlConnection connection = new MySqlConnection(MyConString);
            MySqlCommand command = connection.CreateCommand();
            MySqlDataReader Reader;

            String strCommandText = "SELECT *";
            strCommandText += " FROM homeowners";

            command.CommandText = strCommandText;
            command.CommandTimeout = 21600;
            connection.Open();    // Opening DB connection
            Reader = command.ExecuteReader();
while (Reader.Read()) // Getting Exception on Reader.Read() after a few hundreds iterations
            {
                (range.Cells[12, 3] as Excel.Range).Value2 = Reader.GetValue(ownerNameAndRankFieldIndexInDB).ToString().Trim(); // Owner Name
                (range.Cells[13, 3] as Excel.Range).Value2 = Reader.GetValue(houseNoFieldIndexInDB).ToString().Trim(); // House Number
                (range.Cells[14, 3] as Excel.Range).Value2 = textBoxBillingMonth.Text; // Billing Month
                (range.Cells[15, 3] as Excel.Range).Value2 = textBoxDueDate.Text; // Due Date
                (range.Cells[18, 6] as Excel.Range).Value2 = textBoxServiceCharges.Text; // Service Charges

                ((Excel._Workbook)xlWorkBook).PrintOut(missing, missing,
                    missing, missing, missing,
                    missing, missing, missing);

                // Time taken by printer to process one document
                Thread.Sleep(2000);
            }
            connection.Close(); // closing DB connection

Hi Adil,

This seems similar to issue: http://bugs.mysql.com/bug.php?id=57365

The workaround then was to customize the net_xxx_timeout settings.
For example, issue the following after openning your connection and
before executing the datareader:

MySqlCommand cmd = new MySqlCommand(
  "set net_write_timeout=99999; set net_read_timeout=99999", con );
cmd.ExecuteNonQuery();

Let us know if that solves the prb.

Hi Fernando Gonzalez,
Yeas you are right
It's working like a charm now :)
Thanks a lot

a workaround was provided.

I have the same error, I do what is recommended, but it marking me error, that I can do?
