Hello, some maybe a week or two ago i've started experiencing hangs on my OpenBSD workstation when it is running chromium. at first I didn't recognize the reason, but after some investigation I see that when I have google analytics or some other sites I use regularly, opened in chromium it just eats all the memory available, and never swaps. it wasn't like that a month ago, so I suspect some changes in chromium or may be something was changed in google analytics that prevents system from using swap when it is out of resources.
