What's the default value of "heartbeat_mode" ? process / thread or off? https://docs-v1.prefect.io/orchestration/concepts/services.html#heartbeat-configuration

not 100% sure, but I think default is process, but you can change to thread easily https://docs-v1.prefect.io/orchestration/faq/faq.html#why-does-prefect-mark-flow-runs-with-no-heart[…]from-the-remote-task-marking-the-run-as-failed

Sure. I just wanted to know what the default behavior is 🙂

Not sure if checking out the source-code might give you the answer? https://github.com/PrefectHQ/server/blob/0b64bfd8e6dfc53cddc057575322b3520f1884ea/src/prefect_server/services/towel/zombie_killer.py#L16

Cool, thanks Taylor 🙌
