It's something I'd like to add also for the graceful shutdown, but for now we don't have an easy way to navigate through the idle connections. However something I was considering was to avoid keep-alive when serving a response over a saturated frontend or when the process is stopping. That way existing connections will fade out as new requests are sent over them. Do you think that would already be acceptable in your case ? > I've only found `shutdown session` and `shutdown sessions` commands but > they are obviously not graceful at all. Absolutely. Willy
