The struggle continues. I have two apps. One lightweight, the other more complex - but nothing too dramatic. When using multi-app support, this second one never loads, and crashes Chrome (“Aw, snap”). Run in isolation on its own, it’s fine. Unfortunately, we can only have one uwsgi instance running …
