Fix Application is currently offline

Application is currently offline error occurs in the browser. Offen, when we work with the SQL-Sserver then that's types of problem occurs. When, today i  was develop a new project with the help of SQl. i face this error during demonstration. I want to say that when we retrieve data from database table through Sql DataSource control. I was run my application in browser, error becomes in the browser. Actually its not a error, you can say its a exception, which is detect by the browser. I think, this is overloading exception,  after some time buffer is full so dotnet framework create a page for this types of exception.
