Hello,

I modified the elasticsearch.yml for putting a fix ip address:

network.host : 192.168.15.18

and I modified the /etc/security/limits.conf:

```
elasticuser - nofile 65536
elasticuser - nproc 4096

```

but I still receive this message at the launch of elasticsearch:

```

```

I followed the guide here: [https://www.elastic.co/guide/en/elasticsearch/reference/master/system-config.html#dev-vs-prod](https://www.elastic.co/guide/en/elasticsearch/reference/master/system-config.html#dev-vs-prod)

I already thank you. Regards.

**Ho, and i'm running with Centos 6 btw 🙂**
