The memory consumption of WebkitWebProcess after the browser was closed.

For some reason, the Webkit process keep running and consuming too much memory after closed, I was using two tabs, one running a Youtube video in 480p and another with a google search result.
Using Gnome Web Browser(Flatpak), Version 42.4, WebkitGTK 2.36.4 on Linux Mint 21.

You're certain that web process was created by Epiphany and not some other app?

The web process should quit as soon as its socket to the UI process is closed. That is, this should be impossible. (Of course, it's software... strange things do happen....)

Your web process is using nearly 6 GB of RAM... that's the most I've ever seen, by a lot. What were you doing with it? O_O

I was only watching a video on Youtube and doing some search on google, then suddenly my PC started to get really laggy, then i opened the System Monitor and discovered that the webprocess was eating nearly 6GB of my RAM, i just had open the Pycharm IDE, nothing more.

I am able to reproduce this. On apple.com (reliably reproduced on https://www.apple.com/macbook-pro-14-and-16/), after browsing through the product pages, memory usage increases significantly. After closing the tab, memory usage does not come down. Do that a few times, and my 8 GB of memory as well as the 4 GB of swap are nearly filled up.

This is probably bug #247057, unless you've collected a backtrace to show evidence to the contrary. So I'm going to make it as a duplicate. Still would be good to connect with gdb and see what the web process is doing, so we can know for sure.
