Though, the right value is set for the open file descriptors, the installer still reports requirements not met.

The values mentioned in the snippet do not seem to match [ECE documented installation steps](https://www.elastic.co/guide/en/cloud-enterprise/current/ece-configure-hosts-rhel-centos.html) so I assume some other steps were not followed and might cause this. I would suggest following the appropriate doc depending on the OS and verifying all the steps to prepare the host

Note ulimit should be run inside a docker container if you want to test so it might give more relevant than running on the server directly:

```auto
$ docker run -it busybox sh
/ # cat /proc/sys/fs/file-max

```
