Gracefully stopping varnish

[Guillaume Quintard]

Hi,

That's not possible. However, what you really want, I think, is not sending
new requests to Varnish. That's usually done at the loa-bbalancing level.
If your LB use probes, you can tell Varnish to stop honoring them, drain
the connections,  then kill it.
