title: Mesos-master: Shutdown failed on fd=25: Transport endpoint is not connected [107]
body: <p>When I run 3 mesos-master with QUORUM=2, they fail 1 minute after being elected as the leader, giving errors:</p>
  
  <pre><code>E1015 11:50:35.539562 19150 socket.hpp:174] Shutdown failed on fd=25: Transport endpoint is not connected [107]
  
  E1015 11:50:35.539897 19150 socket.hpp:174] Shutdown failed on fd=24: Transport endpoint is not connected [107]
  </code></pre>
  
  <p>They keep electing one another in a loop, consistently failing and re-electing.</p>
  
  <p>If I set QUORUM=1, everything works well. What could be the reason for this?</p>
