Hi Deepanshu , for Crashed flows I would look to cloud watch - if it’s an infrastructure exception and not flow code, prefect can’t capture the even since it’s a process inside the container .
For 2- I think we would need to see logs and something else - perhaps the job crashed on prefect side but was restarted in k8s side as a retried job ? There is a lot of missing detail to evaluate that one .
3 - do you have any sort of hooks enabled ? Are these sun flows at all ? What version of prefect ? We have seen reports of this happening but haven’t been able to reproduce so any observations and details here are useful
