hi, we're using prefect server as our backend, and using a local agent on our infrastructure to execute flows. we're noticing that for some flows, only the first level of the dag (ie, the tasks with no upstream requirements) get executed, and then nothing happens... any clues as to what might be happening?

Hey @Verun Rahimtoola, Whenever I’ve encountered this, it usually indicates resource constraints in your execution environment if you are running a large flow/processing a lot of data OR network constraints if communication is blocked back to your GraphQL service, but I would also check to ensure you’re running the latest version of Prefect just in case. Normally, the Lazarus process should kick in to mark these tasks as Failed eventually if the tasks can reach Running, so the fact that they never reach this state leads me to believe one of the issues listed above is responsible.

hi @Kyle Moon-Wright thanks for responding! so the agent has no issue talking to the graphql server and getting back flow runs, and i can see this from the agent logs.. also the flow is fairly simple and isn't doing a whole lot 😕 i need to verify with our ops guys if the lazarus service is up and running, as i think that might be the issue... will report back. thanks!
