You lose session data for requests that are currently running when you configure an ASP.NET 2.0-based application to use SQLServer session-state mode

View products that this article applies to.

Symptoms

Consider the following scenario:
  • You configure a Microsoft ASP.NET 2.0-based application to use session state to manage session data.
  • You use SQLServer session-state mode to store session data in a SQL Server database.
  • You configure database mirroring on the SQL Server database.
  • An automatic failover occurs in the SQL Server database.
In this scenario, you lose the session data that was stored in the session state for requests that are currently running. Additionally, you receive an error that resembles the following in the Web browser:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
