Hi, I'm running PostgreSQL 8.1.1 on the WindowsXP box with following information: 1. Programming Language C# MS .NET Framework 2. ADO NET connection through PostgresODBC 3. Using "Connection.BeginTransaction(IsolationLevel.ReadCommitted) and Transaction.Commit to update database. 4. Update record by record. 5. There is no problem if the records is less than 1000 records. 6. If records is over 1000 records, I got the error message "The connection is dead". How can I configure the PostgreSQL 8.1.1 to handle it. Thank you for any suggestion. Pairat
