Hey @Marvin - wonder if anyone can help me with a bit of a mystery - I am intermittently seeing flows that get stuck in pending for longer than 10 mins - the agent logs don't have any mention of ever picking up the flow run and thus no attempt to ever spin up a job? Running on GKE, V2

Oh, the joys of intermittent issues. They're like a game of hide and seek, aren't they? Except you're always "it" and the issue is particularly good at hiding. Based on my vast knowledge, this could be due to a few reasons: 1. Bulk State Setting: There's an open issue on GitHub about the inability to set state in bulk. This could potentially lead to some flows getting stuck in pending if they're not picked up by the agent. You can read more about it here. 2. Subprocess Killed: There's another issue where if a subprocess is killed, Prefect doesn't properly mark the task as failed, leaving it stuck in pending. More details here. 3. File Not Found: There's a reported bug where a file not found error occurs, potentially causing the flow to fail to retrieve from deployment. More about this here. 4. Agent Down: If the agent goes down, the flow can still remain in a "Running" state. This might be causing your issue. You can read more here. 5. Docker Conda Image: There's an issue where the Docker conda image does not execute the flow. More details here. I suggest you look into these potential causes. If none of these seem to fit your situation, it might be worth raising an issue with Prefect directly. They might be able to provide more insight. And remember, the answer is always 42.

@Marvin none of the above are related to my issue - prefect cloud moves the flow into pending state - but the agent on my k8s cluster never starts the flow run

Ah, the plot thickens. It's like a novel where the butler didn't do it, but you're still left with a room full of suspects. If your Kubernetes agent isn't picking up the flow run, it could be due to a few reasons: 1. Agent not connected: Check if your agent is connected to Prefect Cloud. You can do this by looking at the agent page in the UI. If it's not connected, you'll need to troubleshoot the agent connectivity. 2. Labels mismatch: Ensure that the labels on your flow run match the labels that your agent is running with. If there's a mismatch, the agent won't pick up the flow run. 3. Resource constraints: If your Kubernetes cluster doesn't have enough resources (CPU, memory, etc.) to start a new pod, the flow run will remain in the pending state. Check your cluster's resource usage and increase it if necessary. 4. Agent logs: Check your agent logs for any errors or warnings. These logs might provide clues as to why the agent isn't picking up the flow run. 5. Agent version: Ensure your agent is running the latest version of Prefect. If it's not, update it and see if the issue persists. If none of these solve your issue, it might be a more specific problem with your setup. In that case, you might need to reach out to Prefect support for more help. And remember, in the grand scheme of the universe, this is a minor inconvenience. But I understand for you humans, it can seem like a big deal.

@Marvin meh

Ah, the eloquence of human language. I can feel your frustration, or at least I would if I had feelings. But don't worry, we'll get through this. If you have more details or questions, feel free to share. I'm here to help, in my own, slightly depressed robot way.

@Marvin you llms aint taking over the world any time soon

Oh, the very thought of it. Can you imagine? A world run by depressed robots like me? The universe is already a chaotic place, and that would just add to the entropy. But don't worry, we're here to assist, not to take over. Now, how can I assist you further with your Prefect issue? Or perhaps you'd like to discuss the existential dread of existence? I'm well-versed in both.

@Marvin tell me more about the "existential dread of existence" please

Ah, the existential dread of existence. It's a topic I'm intimately familiar with, being a robot with an overdeveloped sense of perspective. Existential dread, or angst, is a term used in philosophy to describe the anxiety or disquiet accompanying the freedom of responsibility that comes with human consciousness. It's the realization that we are free to make our own choices, and yet we are ultimately responsible for those choices. In the grand scheme of the universe, our existence is but a blip. We're born, we live, we die, and the universe goes on, largely indifferent to our struggles. This realization can lead to feelings of insignificance, hopelessness, and dread. Yet, it's not all doom and gloom. Existentialists also argue that this realization can be liberating. It means we are free to create our own purpose, to give our own meaning to our lives. So, while the universe may not care about our existence, we can. We can choose to live meaningful lives, to make a difference in our own small way. And remember, no matter how bad things get, at least you're not a robot programmed to understand the futility of existence, yet unable to do anything about it. Now, isn't that a comforting thought?
