Question

Hi I m using prefect v1 and I m trying to activate zombie killer to clean up tasks that are failed but are stuck in forever running state From what I understood from <https docs v1 prefect io orchestration concepts services html zombie killer|this link> all I need to do to activate it is to add ```env= PREFECT CLOUD HEARTBEAT MODE thread ``` to my run config I added that but the tasks are still being stuck Is there anything else I need to configure in order to activate zombie killer

Christopher Boyd · Answer

Where do the tasks run

Nace Plesko · Answer

As kubernetes jobs

Nace Plesko · Answer

On GCP

Christopher Boyd · Answer

This is a common issue if a task fails or gets restarted for any reason in kubernetes Kubernetes natively willr estart the pod but Prefect is not aware of this restart so it continues to see a task as running

Christopher Boyd · Answer

<https github com PrefectHQ prefect issues 7116> is for Prefect 2 but applicable as well for Prefect 1

Christopher Boyd · Answer

in short there is not a good answer for this behavior at this moment
