This repository contains reproduction instructions for an issue with Fastify websockets where closing the Fastify instance does not trigger the preClose or close events and causes the server to hang indefinitely.

The root cause appears to be having a live websocket connection to a secondary binding which causes the close hooks to pause indefinitely while the connection is live. This causes the shutdown process to timeout and fail.

1. Run node index.js
2. Open index.html
3. Ctrl-C the node process

Expected: Fastify shuts down cleanly Observed: Fastify hangs and has to force a shutdown through process.exit(1)
