title: Timeout::Error: execution expired with Capistrano/Rubber
body: <p>We have been using the rubber gem to deploy to AWS for months and we are now suddenly getting a <code>Timeout::Error: execution expired error</code> with Capistrano. I've tried downgrading <code>net-ssh</code> to 2.7 and that didn't help. I believe the old net-ssh 2.8 has been resolved for awhile now and we are use 2.9.1 (and have been for awhile).</p>
  
  <p>I'm able to SSH into the instances with no problems. Has anyone ran into similar issues? Is there something else I should check that could lead me in the right direction?</p>
  
  <p>Thanks!</p>
