title: WCF connection limits
body: <p>We have a WCF net.tcp service in high traffic site.
  <a href="http://www.artedelcorpo.com/" rel="nofollow">http://www.artedelcorpo.com/</a></p>
  
  <p>It works very well for some time, then it stops and returns a timeout error.
  When I restart IIS, it runs again.</p>
  
  <p>Why?
  Is there a limit on connections?</p>
