Between connection.Open(); and command.ExecuteNonQuery(); I just added two lines like this:

Code:
connection.Open();

MySqlCommand cmd = new MySqlCommand("set net_write_timeout=99999; set net_read_timeout=99999", connection); // Setting tiimeout on mysqlServer
cmd.ExecuteNonQuery();

int numOfRecordsUpdated = command.ExecuteNonQuery();
Problem Fixed
