My droplet is out of memory

A $5 droplet isn’t enough to host Docker apps. I upgraded to a $10 instance and these errors doesn’t show up anymore.

Hi @rameshbhalla81,

Do you have SWAP configured? If not I would recommend you to do so.

Swap is an area on a hard drive that has been designated as a place where the operating system can temporarily store data that it can no longer hold in RAM. Basically, this gives you the ability to increase the amount of information that your server can keep in its working “memory”, with some caveats. The swap space on the hard drive will be used mainly when there is no longer sufficient space in RAM to hold in-use application data.

You can follow this tutorial here to see how you can add it:

Heya,

I’m sorry to hear about your experience. If you’re having issues with processes being killed due to memory issues you can start with examining the logs and also monitor the resource usage on your droplet.

You can check this article on how to monitor the resource usage on your droplet:

Tools like MySQL Tunner can help you to optimise the configuration of the MySQL service by adjusting the values in the my.cnf file.

You can find more information about the MySQL tunner script in this mini tutorial here:

Adding a swap file can also benefit the performance.
