title: Build() or Update() can only be called once on a ContainerBuilder
body: <p>We are currently using autofac in our mvc web app.</p>
  
  <pre><code>Build() or Update() can only be called once on a ContainerBuilder
  </code></pre>
  
  <p>Every 1-4 days we get the error noted above. It's driving me crazy. I've been trying to see why it would be doing this but I can't pinpoint the issue. </p>
  
  <p>Can someone point me in the right direction.</p>
