We do this too, attaching req and res objects to a domain, as well as databases and other network related objects (like smtp clients, etc). This is a huge improvement, but I'm still seeing occasional uncaught error events in our logs on a very large codebase and only in production. Some of them are just ECONNRESET events with no details given, so their origins are REALLY hard to track down. Have you got some magic for catching everything without explicitly having to find all objects that could be emitting? I'd love to hear it if so...
