positive.code: === 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:
