19+Urbit wants to map 2GB of memory when it boots up. We won’t
20+necessarily use all this memory, we just want to see it. On a
21+normal modern PC or Mac, this is not an issue. On some small
22+cloud virtual machines (Amazon or Digital Ocean), the default
23+memory configuration is smaller than this, and you need to
24+manually configure a swapfile.
26+Digital Ocean has a post on adding swap [here](https://www.digitalocean.com/community/tutorials/how-to-add-swap-on-ubuntu-14-04). For Amazon there’s a StackOverflow thread [here](http://stackoverflow.com/questions/17173972/how-do-you-add-swap-to-an-ec2-instance).
