4.27.0 introduced a change that prevents the event loop from being cleaned up properly

See original GitHub issue

https://github.com/evanlucas/ioredis-sentinel-hang is how I was able to reproduce it. We rely on calling quit in all of our jobs/workers/services and if the event loop is not cleaned up, it prevents node from cleanly exiting the process. It looks like it is the new failover detection mechanism that was added. I’m seeing additional TCP sockets being opened, but never closed.

This only seems to occur when using redis sentinel.

Thanks!

Hey @evanlucas, thanks for the reproducible repo! Calling .disconnect() should properly clean up everything. We should take a look for a fix for quit.
