Description Debarshi Ray 2016-10-27 22:06:39 UTC 
The system starts swapping heavily and becomes unusable as new tabs are opened. I see a lot of entries in the journal with the "Memory pressure relief: " prefix, which makes me suspect the new memory pressure handling in webkitgtk.

Versions:
epiphany-3.20.4-1.fc24.x86_64
webkitgtk4-2.14.1-1.fc24.x86_64

I know that it is swapping because kswapd0 consumes more than 80% CPU in top(1).
Comment 2 Michael Catanzaro 2016-10-27 22:28:37 UTC 
Interesting timing, we just noticed this earlier today.
Comment 3 Michael Catanzaro 2016-10-27 22:29:50 UTC 
By the way, I think this is only a problem in single secondary process mode; did you enable that hidden option?

$ gsettings get org.gnome.Epiphany process-model
