Hey we re seeing some duplicate flow runs got any ideas more info in thread

Lukas N. · Answer

Hi did a quick scan in history and couldn t find an answer to it We re running a `KubernetesAgent` and we have more than one replica I think it leads to a single flow run being deployed multiple times Are we supposed to have only one replica or is there another solution Went through the Prefect code and found only this <https github com PrefectHQ prefect blob 45100bc667d04986226446a2f2dfbbfd1e529c26 src prefect agent agent py L522|bit> where it checks for duplicates but only in the agent threads but not across multiple instances of agents So if multiple agents query for flow runs at the approx same time they will both deploy the same flow run is that right

Hi Lukas are you using Server or Cloud

Lukas N. · Answer

Hi Chris I m using Server

Chris White · Answer

Ah ok on Server you should only have a single replica as Server is designed for single node single user deployments In Prefect Cloud there is a locking mechanism on Submitted states that prevents these duplicate deployments

Ah I see that was what I expected thanks +1
