title: An operation was attempted on something that is not a socket
body: <p>I have a web application with 2 tabs, and on click of each tab, I connect to the database, and fetch some information. Each tab sends a full HTTP Post request to the server and of course, web latency is the nature of web development.</p>
  
  <p>Sometimes when I click rapidly between tabs, change tabs as fast as possible, I get this error from SQL Server:</p>
  
  <blockquote>
    <p>A transport-level error has occurred when sending the request to the server. (provider: TCP Provider, error: 0 - An operation was attempted on something that is not a socket.) </p>
  </blockquote>
  
  <p>This is the first time I've seen this error. What's wrong? I'm using LINQ to SQL to connect to DB and nothing fancy is in action. I just have an ordinary web application.</p>
