Hi,

in order to disable swapping of Elasticsearch memory, the file You mentioned should contain:

`[Service]`  
`LimitMEMLOCK=infinity`

This is described in the [ElasticSearch Reference](https://www.elastic.co/guide/en/elasticsearch/reference/current/setting-system-settings.html#systemd), but I also did not find it right away.

We also set there the NOFILE limit for Elasticsearch:

`LimitNOFILE=65535`

Hope, that helps!  
Alex
