See server product listing falls

Hi everyone, I hired a VPS with 2GB of ram, I created a website that for now only I can access.

Everything works fine in Wordpress + Wocommerce, but when I access the page /shop where the products are listed, the server changes its behavior, memory goes to 100% and CPU goes to 100% also locks the server and it only works again by restarting.

The cause of this is the Mysql service that when I click to show the pages it comes into action and locks everything up.

I have other servers the same with the same plugins and themes and this error does not occur, what could this be?

Somebody help me =)

I thank you all.
