https://docs.prefect.io/orchestration/concepts/flows.html#toggling-heartbeats we are running into a task that is long runing ~ 1hr that is getting killed by the zombie killer
Hi @DJ Erraballi - this is usually a result of your machine/node/worker running into resource constraints that prevent it from sending updates to the server. If you're confident that the task is still running as you expect, you can certainly turn off heartbeats for the flow. However, resources constraints are usually the place I'd look first to figure out what might be going on, else you can end up with runaway tasks that aren't performing what you think they are.
Also in the future, if you could combine your messages into one or use the thread, it's helpful for discoverability!
👍 for sure thanks
