Have you set botstrap.mlockall: true in your elasticsearch.yml?

This can be caused be a resource limit on the Elasticsearch user. They are
simply not allowed to lock that much memory. Have a look at how the deb or
rpm set the limit.

If you install the RPM it'll run as the Elasticsearch use by default.
