anchor.diff:  === Error on starting Hawkular- OutOfMemoryError: unable to create new native thread
   This may happen if you use Cassandra embedded with Hawkular on *x systems
   
  -Cassandra requres `ulimit` settings that are higher than usual on common *nix distributions. First check your present limits with `ulimit -a` and eventually increase open files to 65535 and max user processes to 4096 as appropriate on your system.

   On RHEL, CentOS and Fedora the settings can be made persistent in `/etc/security/limits.conf` like this:
   ----
  
positive.code: <3> Download has finished, Hawkular server will be started
  <4> Hawkular server has started with a container id of `c792a1f0595`. This id will be different for each start.
  
  Now as Docker is running the container and you can reach the Hawkular UI at http://localhost:8080/  
  
  NOTE: If you are running docker on OS/X via boot2docker, you need to use the IP address that is stored in the `DOCKER_HOST`
  environment variable instead of `localhost`.)
