The VM that runs this website is on DigitalOcean. It’s so old (3 years) that it was only provisioned with 1CPU\/512MB of memory. This has been sufficient but it’s a tight squeeze with the reverse proxy and MySQL shoehorned onto the same VM. Tonight when I ran OS updates, I noticed this website went down. After looking further, the Linux OOM killer had stepped in and killed MySQL to keep the machine up and running. After starting MySQL, I scaled the droplet to a larger size.<\/p>\n\n\n\n
DigitalOcean allows you to scale your droplet but they cannot perform hot add, so the droplet needed to be powered off. Luckily, the $5\/mo droplet size has increased to 1CPU\/1GB so I was able to double this VMs memory at no cost. <\/p>\n\n\n\n
