I'm not arguing or anything, but that's what I observed and recorded during load testing. Not just once but load testing over weeks, conducted by not just me but a whole team of developers.
Node.js itself will not crash if hitting open file limit, but some sockets will hang up, and response get slower, etc. No matter what, one of the solutions is to increase the open file to ...e.g. over 10K. then you will be safe in most cases.
