Hi guys,  
I'm having problems with the bootstrap check on a RedHat box. I've searched around the forums and tried

```
[2017-09-20T11:40:41,836][ERROR][o.e.b.Bootstrap] [node1] node validation exception
[2] bootstrap checks failed
[1]: memory locking requested for elasticsearch process but memory is not locked
[2]: system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk

```

I have set the following in /usr/lib/systemd/system/elasticsearch.service

`LimitMEMLOCK=infinity`

And in /etc/security/limits.conf I have

```
elasticsearch hard memlock unlimited
elasticsearch soft memlock unlimited
elasticsearch - nofile 65536

```

What am I missing?

Thanks in advance!

Matt
