Thanks for the feedback - It was a systemd issue. Something caused it to continue generating slices for espanso until the machine locked up - probably spawned with each terminal. It happened on out of date fedora install 36 (when 41 was out) with gnome on it.
Since then I’ve moved to a window manager for all my machines and would likely invoke it the same way - perhaps now it’s time to revisit!
Well, apparently Meta’s pixel tracking script was bypassing that VM and SELinux enforcment to exfil tracking impressions for years and doing it by creating webRTC dummy ports, that were chatting with their own apps (Instagram, Facebook, ?WhatsApp?-not sure). So not sure this was a great implementation to begin with.
And this was working despite sandboxing on other browsers
