Docker WordPress CPU jumps when selecting featured image

I have a DO VPS with 1GB RAM and 1 CPU.

I started to see some issues when I selected a Featured Image. I lost the database connection, so I checked my stats both docker and DO CPU stats, and shortly after selecting an image of around 1meg in size, my wp container’s CPU skyrocketed and either caused the memory to run out or just did not do anything?
