title: Project Collection Build Services locking my files
body: <p>I'm sorry if I'm misunderstanding the problem but I'm relatively new to TFS and am having some locking issues.  When I'm trying to save/change my files, I get an error that says:</p>
  
  <blockquote>
    <p>Cannot lock items, the item is checked out by Project Collection Build
    Service.</p>
  </blockquote>
  
  <p>What are some of the reasons this may be happening? This happened shortly after I queued a new build.  </p>
  
  <p>Thank you.</p>
