Hello David, so far nobody responded to this e-mail. Maybe you can make a pull request from it, just to not loose it. Then developers could review and comment on it.
Cheers, Henning From: David Villasmil via sr-dev <sr-dev@lists.kamailio.org> Sent: Sonntag, 11.

The patch creates a new core cfg variable which, if set, will reject any incoming NEW tcp connection attempt, so we can use this to gracefully drain kamailio.

I’m thinking maybe we can add this feature?
