See this FAQ.

@daffl I love those kinds of answers. Go elsewhere and two years later that elsewhere doesn't exist...

The elsewhere can still be found at the documentation for the version you are using (e.g. https://crow.docs.feathersjs.com/help/faq.html#possible-eventemitter-memory-leak-detected-warning). However, for the version the documentation is now covering this error will no longer occur at all. I updated the link accordingly.
