Why timeout may occur in SqlConnection.Open()?
问题 What are the cases when timeout occurs in SqlConnection.Open()? On one of our IIS boxes 10 seconds after AppProcess was recycled the following exception appeared: Type : System.Data.SqlClient.SqlException, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 Message : Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. Source : .Net SqlClient Data Provider Help link : Errors : System.Data.SqlClient
