System.Net.Sockets.SocketException: An established connection was aborted by the software

Hello, I got this error today in an Application. This app is coded in asp.net 2, using VB. I have the Andri Code (http://makoto.madmedia.ca/2007/03/mysql-membership-and-role-provider-for.html) to connect asp.net with mysql. It has never caused errors in the past, I have the same configuration on another app that has been running for several months with no problem.

This app is new (1 week) and today is the first day I see this error.

Any ideas?

Server Error in '/' Application.

Do you have a firewall on your machine? This may be preventing your app from accessing MySQL via TCP/IP.

One other problem where I received this error was when I built a client/server app, and one machine had IPv6 protocol installed but the other machine had IPv4 (same domain/network). When I changed both to IPv4, it worked.

Hello, I have other apps with the same configuration running in the same machine so I think the firewall is not an option.

This is not a standalone app, it is a web app.

Hi vialetti,

I am afraid to say that it seems a bug said from MySql community. Here is link:http://bugs.mysql.com/bug.php?id=6634

Hope this helps. Thanks.
