Hi I am starting to randomly see this on flow runs;

```12:09:39 ERROR prefect-server.ZombieKiller.TaskRun No heartbeat detected from the remote task; marking the run as failed.
12:22:53 INFO prefect-server.Lazarus.FlowRun Rescheduled by a Lazarus process. This is attempt 1.```
I am running on GKE autopilot - any ideas how to debug cause of such events and mitigate against their occurence?

Happens rarely but once or twice every few days

I see this has been written up about it <https://discourse.prefect.io/t/flow-is-failing-with-an-error-message-no-heartbeat-detected-from-the-remote-task/79> - so from this description I should try setting the heartbeat mode to thread - but this may not solve?

Yes that’s exactly right. Thread will be more stable but you may be running into issues where the task is dying due to memory issues
