How about adding some swap into system?

Hey all,
I have 3 web servers hosted at Digital Ocean that all have the same amount of memory at 512MB. They're all running CentOS 7.
They are low powered apache servers and don't really need more than that. All they're doing is serving the web, no database on those hosts at all.
On the first two hosts I seem to have no trouble running SELinux related commands. It's only on the 3rd web server where I seem to have any trouble at all running the SELinux commands I want to keep the box secure.
On box #3 all SElinux commands end up the same way. For example:
[root@ops3:~] #semodule -i newrelic.pp Killed
And that happened when I had about 280MB free:
[root@ops3:~] #free -m total used free shared buff/cache available Mem: 490 96 286 28 107 285 Swap: 0 0 0
Typically what I'll do is stop all the main services on this machine to free up some memory to run the command I want. But to no avail! The commands die with the same errors every time. Whereas on the other two hosts I can run the same commands with only as little as 30 or 40MB free!
So would this be some inherent flaw with this box? That the only way to get around it is to scrap it and build a replacement?
Not that hard to do. But before I took that measure I was wondering if there was any hocus-pocus I could try that I might not be aware of that could alleviate this scenario.
Thanks, Tim
