  <p>This thread seems to say it's something wrong with Master/Slave:
  <a href="https://groups.google.com/forum/?fromgroups=#!topic/jenkinsci-issues/MaMqjK3iW8Y">https://groups.google.com/forum/?fromgroups=#!topic/jenkinsci-issues/MaMqjK3iW8Y</a></p>
  
  <p>But it doesn't really offer a solution. The Jenkin slave says it's connected and it's reflected on the Jenkins project page.</p>
