title: Teamcity does not collect Changes after one build is finished
body: <p>We use Teamcity for our build integration.
  Currently we're fighting with an error.
  Our Teamcity is running and also an agent runs.
  When we commit something into the svn, teamcity collects all changes and then builds all of our sources.
  After this process is finished, the svn isn't checked anymore. The agent remains pending all the time.</p>
  
  <p>How can we achieve that the agent will listen to svn changes?</p>
