ORA-12571: TNS: Packet writer failure with ASP .NET 4.0

783625Jul 7 2010 — edited Aug 22 2012

Hello everyone! I really need urgent help here!
I have an ASP .NET Web Application (4.0) and when someone makes an insert or update operation in any page, the Oracle Client returns this message:

Oracle.DataAccess.Client.OracleException ORA-12571: Packet writer failure

The real issue is that this error doesn't show eveytime, it only shows when the user opens the page, wait some minutes and makes the operation. When the user opens the page and immediatly makes the operation, everithing goes well.

I have tried everything: reistall the client, try with the Web site in another server, disabling the antivirus in the server and specifying the database server in TSNAMES.ORA file. Nothing works! The error keeps displaying eventually!

What else can I do?

Thanks in advance!
