I know that we can use
sv stop unicorn then
sv start unicorn to restart unicorn workers. But that will cause downtime. Killing the master with a
USR2 signal is the usual way to do hot restart, as far as I know. Is it still safe to do that for Discourse? Or is there a better way to do this?
I understand that I rarely (or not at all) have to do this. But just want to know in case of emergency.
