Hi, as es official web site stated, it is strongly recommend that **bootstrap.mlockall: true** should be set in elasticsearch.yaml file. but after restart es, I find that the setting is not effective as below graph ![](https://us1.discourse-cdn.com/elastic/original/2X/b/bbebf1dfdf4a2e0747a7b5b86293c4f3c4527dcc.png) es is restarted with an user rui rather than root, I doubt that rui has no permission to make **bootstrap.mlockall: true** to take effect. So what I can do with that? Any help will be appreciated! Thanks a lot in advance ---

Where did you set it? Did you set heap min/max the same? ---

I set the property in elasticsearch.yml as below graph ![](https://us1.discourse-cdn.com/elastic/original/2X/f/fc1c8d2fe3693b2f80b93aa39d5a2dcacee3ff3f.png) For heap, I set the envrionment ES\_HEAP\_SIZE=3g. And I start ES by the user **rui** with Supervisord ![](https://us1.discourse-cdn.com/elastic/original/2X/4/4d9abe0e281770ff2ad590fe41c0415000a1a879.png) ---

Hi warkolm,I set the property in **/opt/modules/elasticsearch-2.3.3/conf/elasticsearch.yml** as **bootstrap.mlockall: true** , and restart es via supervisord, the conf of which is as **command=/opt/modules/elasticsearch-2.3.3/bin/elasticsearch --network.host 0. 0.0.0** **user=rui** but after restarting, I see the below result in \_nodes/process?pretty: "M\_r6PeG4TraVpfUeoZnmOA" : { "name" : "node-2", "transport\_address" : "10.172.95.65:9300", "host" : "10.172.95.65", "ip" : "10.172.95.65", "version" : "2.3.3", "build" : "218bdf1", "http\_address" : "10.172.95.65:9200", "process" : { "refresh\_interval\_in\_millis" : 1000, "id" : 10305, **"mlockall" : false** I want to ask why? Thanks a lot! ---
