title: Wildfly Docker Container Live Migration with CRIU fails
body: <p>I'm trying to live migrate a wildfly docker container to another host like described <a href="https://circleci.com/blog/checkpoint-and-restore-docker-container-with-criu/" rel="nofollow noreferrer">here</a>. The np-example runs very well. </p>
  
  <p>This is my container</p>
  
  <pre><code>docker run -itd -p 8081:8080 -v /tmp/docker/:/opt/jboss/wildfly/standalone/deployments/:rw --name=mywildfly jboss/wildfly
  </code></pre>
  
  <p>But when I try to checkpoint it, I get this error</p>
  
  <pre><code>docker checkpoint mywildfly
  Error response from daemon: Cannot checkpoint container mywildfly: criu failed: type NOTIFY errno 0
  Error: failed to checkpoint one or more containers
  </code></pre>
  
  <p>Even a suspended wildfly server and a container without port forwarding and volume sharing cannot be checkpointed. </p>
  
  <pre><code> docker run --name=wildfly -itd jboss/wildfly
  </code></pre>
  
  <p>Can anyone tell me how to find a log file to specify the error. </p>
  
  <p>Thanks in advance</p>
