title: Docker daemon fails to restart gracefully
body: <p>Been seeing an intermittent issue with one of my docker deployments.  Basically, the docker daemon fails to restart gracefully.</p>
  
  <p>From syslog:</p>
  
  <pre><code>init: docker main process ended, respawning
  init: docker main process (14333) terminated with status 1
  init: docker respawning too fast, stopped
  </code></pre>
  
  <p>From docker upstart log:</p>
  
  <pre><code>FATA[0000]  Error starting daemon: error initializing network controller: could not delete the default bridge network: network bridge has active endpoints
  /var/run/docker.sock is up
  </code></pre>
  
  <p>I can fix this issue by running:</p>
  
  <pre><code>sudo rm -r /var/lib/docker/network
  sudo service docker start
  </code></pre>
  
  <p>This is running on Ubuntu 14.04.3 on 3.16.0-48-generic using Docker 1.10.0.</p>
  
  <p>Any ideas on a permanent fix for this?</p>
  
  <p>Thanks!</p>
