I changed the heartbeat mode and it has way way more memory than it needs but its still ocsasionally failing with ```09 08 48 INFO CloudTaskRunner Task insert Starting task run 09 08 48 INFO CloudTaskRunner Task insert Finished task run for task with final state Pending 09 08 48 INFO CloudFlowRunner Flow run RUNNING terminal tasks are incomplete 09 57 00 ERROR prefect server ZombieKiller TaskRun No heartbeat detected from the remote task marking the run as failed ```

Joshua we are aware that the heartbeat experience is not the best one and it s on our radar to improve the UX in Prefect 2 0 <https discourse prefect io t flow is failing with an error message no heartbeat detected from the remote task 79|this topic> explains the problem and shows some possible solutions but that s all we have currently as a remedy to this issue

Joshua Greenhalgh · Answer

Yeah I have tried all of these increased memory at least 2x what it needs changed the heartbeat mode to `threads` not sure what else I can do

Joshua Greenhalgh · Answer

Is this just something I am going to have to live with happening occasionally

Anna Geller · Answer

I guess so all the solutions I m aware of are in this Discourse topic and I m aware they aren t perfect but that s all we have it s a difficult problem that we don t have the capacity to tackle in more depth in 1 0 but we ll do in 2 0

< Anna Geller> do you have any sense of the downsides of turning off heartbeat altogether when I know the task is just long running Would it be better to turn it off altogether at the flow level or to use mutations to turn off before the task in question and then turn it back on after

Anna Geller · Answer

Afaik the downside is that if this task run gets stuck Zombie Killer won t try to kill and restart it

Joshua Greenhalgh · Answer

But if I am certain I don t want that behaviour then thats fine
