The most common reason for MySQL to become unavailable or crash is a lack of available memory. If you are running a LAMP stack on a small droplet this can occur since droplets do not have a swap partition to use when the physical memory has been exhausted. There are a few things you can do to resolve this:

1.) Upgrade to a larger droplet plan.
2.) Set up swap space on your droplet.
3.) Optimize your MySQL and Apache processes.
