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, but I also did not find it right away.

We also set there the NOFILE limit for Elasticsearch:

LimitNOFILE=65535

Hope, that helps!
Alex
