Increase swap on Ubuntu
Raw
_increase_swap.md

My Vagrant Ubuntu VM just died while running a memory intensive command.

Its output just says "Killed".

vim /var/log/syslog confirms that the machine ran out swap and the process was killed.

free -m shows we have 768M (or so) swap space.

sudo swapon -s shows that we have a single swap partition at /dev/mapper/precise64-swap_1

The steps to temporarily add an extra swap partition:

sudo fallocate -l 3G /swapfile
sudo chmod 600 /swapfile
mkswap /swapfile
swapon /swapfile
