Hi folks. I'm seeing if I can get ES5 set up in a very limited environment (2Gb RAM) I have a clean install of Ubuntu 16.04, and have installed ES 5.0.0. I have configured ES to start with systemd. In /etc/elasticsearch/elasticsearch.yml I have set `bootstrap.memory_lock: false` In /etc/elasticsearch/jvm.options I have set `-Xms1g` and `-Xmx1g` In /etc/default/elasticsearch I have set `MAX_LOCKED_MEMORY=1g` When I start the service, the elasticsearch log shows some errors seemingly about memory: > [2016-11-08T10:22:52,717][INFO][o.e.n.Node] [linode1] initializing ... > [2016-11-08T10:22:52,867][INFO][o.e.e.NodeEnvironment] [linode1] using [1] data paths, mounts [[/ (/dev/root)]], net usable\_space [21gb], net total\_space [23.4gb], spins?

Aah, it's the last one of those that I missed! Thank you. > sysctl vm.max\_map\_count=262144 ---
