I am running into the exact same issue as the topic above, on a 2GB ram instance.
Right before the error, I made a htop snapshot - notice swap is not being used.

You need 2gb swap. If you ran discourse-setup it would have created it

Should’ve stated that this is running for 4 years+, I rebuild every 2/3 months.

Yep, swap is critical.
Things will fail without it.

So basically run discourse-setup again instead of a regular rebuild?

If you ran `discourse-setup` to start then perhaps there is something about your system that kept it from creating swap. You might need to just create the swap yourself. Google something like “create swap YOUR-LINUX-DISTRIBUTION”

Thanks Jay & Robert. Indeed the swap was missing.
Solution is:
```plaintext
cd /var/discourse
chmod 700 containers # might be redundant, but no harm
./discourse-setup
```
The setup will recreate the swap and exit.

So you originally installed without running `discouse-setup`?

No, I used `discourse-setup` a few years ago to install this instance. I am not sure why the swap is killed, I did install something else on the server a while ago, which is now uninstalled, it may have done something I’m not aware of. Maybe this app interacted with swap, not my field of expertise, but the instance is up and running again.
