That's what web application servers normally do when you start them. That's why it happens in your case. How do you stop it? Well, as you say it isn't a problem...
The only thing being "started" is the web container. e.g. Tomcat.
Think of it as a shop. You open the shop in the morning and all the items on display are available for purchase. If you don't want to sell something, take them off the shelf.
