Did you fix that nom thinks there are way more roots than there actually are? aka https://github.com/maralorn/nix-output-monitor/commit/90fd896e82ce8fe1faa439d3024e950ae488da54
seems to be a lot more stable and predictable. Also the ca errors seem to be gone for the moment but maybe things that use ca are currently cached for me.
