How to force to kill replica in ray serve instead of waiting for health check

Ray Serve
1

if something wrong while the request processing, how I can kill the replica myself?

I know that I can implement my own check health function, but check health also need to wait for the health check period until it get killed, which might handle some requests during this period.

how I can immediately kill the replica if I find something wrong during the request?

Hmm I’m not really sure if there are cases you would want to kill the “replica” when the request goes wrong (as opposite to kill the “request”).

If the default health check period is too long, can you configure health_check_period_s on your deployment to have a shorter time doc: Configure Ray Serve deployments — Ray 2.43.0

If you really want to kill a replica outside of Serve’s control, you can kill it just like any Ray actors. Something like this should work

handle = ray.get_actor(actor_name, namespace=SERVE_NAMESPACE)
handle.perform_graceful_shutdown.remote()

Hope this helps

Thanks. I’m now using the sys.exit(0). it seems working fine
