# Hardware & OS

Run on any Linux server (review ulimits or container technology (docker/kubernetes). For RHEL 6.x and CentOS 6.x use docker.

Linux machines typically have a soft limit of 1024 open file descriptors. Check your current limit with the **ulimit** command:

```bash
ulimit -S -n     # soft limit
ulimit -H -n     # hard limit
```

Increase as a super-user the soft limit to 4096 with:

```bash
ulimit -S -n 4096
```
