@Marvin Why do i see this in my workers log? <error> 124257.250 | DEBUG | APILogWorkerThread | prefect._internal.concurrency - Encountered exception in call get(<dropped>) Nov 27 124257 prefect-vm poetry[1413]: Traceback (most recent call last): Nov 27 124257 prefect-vm poetry[1413]: File "/home/prefect/source/.venv/lib/python3.11/site-packages/prefect/_internal/concurrency/calls.py", line 346, in _run_sync Nov 27 124257 prefect-vm poetry[1413]: result = self.fn(*self.args, **self.kwargs) Nov 27 124257 prefect-vm poetry[1413]: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Nov 27 124257 prefect-vm poetry[1413]: File "/usr/lib/python3.11/queue.py", line 179, in get Nov 27 124257 prefect-vm poetry[1413]: raise Empty Nov 27 124257 prefect-vm poetry[1413]: _queue.Empty </error>

The error message you're seeing in your worker logs suggests an issue related to the Python queue's "Empty" exception. This typically happens when a call to

get()

on a queue is made, and the queue is empty, resulting in the

_queue.Empty

exception being raised. There isn't an exact match in the current GitHub issues, but here are a few potential reasons and tips to resolve or investigate further: 1. Queue Handling: The error may occur if the function or task attempts to get an item from the queue, but there's nothing there. If you're handling a queue, ensure that you're managing queue operations properly, and consider checking if the queue is empty before calling

get()

. 2. Concurrency Issues: Since the error seems to occur in the context of concurrency, make sure that the concurrent processes or threads are coordinating correctly. Debugging concurrency issues can be tricky, so logging the operations around the queue can help isolate the problem. 3. Prefect Version: Ensure you're using a compatible version of Prefect with your infrastructure. You might want to check the latest release notes or documentation on concurrency handling for any related updates or patches. 4. Code Examination: Reviewing the related code sections where this error occurs might help. It might be useful to add exception handling around the line throwing the error to gracefully catch and log more contextual information. 5. GitHub Issues and Documentation: It could be useful to check Prefect's GitHub Issues and Documentation for similar error reports or more detailed explanations of the concurrency features if you haven't already. If the above tips do not resolve your issue, you can consider raising a new issue on Prefect's GitHub repository with detailed reproduction steps. Here’s a general page to explore current issues: Prefect Issues Page.

@Marvin is this something to do with prefects library or my setup?

The error in your worker logs is likely related to how concurrency and queue operations are being managed within your setup using the Prefect framework. However, the root cause could be specific to either the Prefect library itself or your particular configuration and implementation. Let's break it down: 1. Prefect Library: If this issue is due to a bug or a known limitation in the Prefect library, it might have been encountered by other users. If this is the case, you'd typically find related information in the GitHub issues, release notes, or documentation. Although I didn't find an exact match for your specific error in the issues, it's worth keeping an eye on any updates from the Prefect team. 2. Your Setup: It's also possible that the error is specific to your setup. This could include how tasks or flows are implemented, how concurrency is managed, or how the environment is configured (e.g., versions, dependencies, system resources). If you have access to logs or monitoring tools, examining the behavior around the time of the error might shed light on whether something in your setup needs adjustment. To further narrow it down: - Consider testing your code in a different environment to see if the issue persists. If it disappears, it might be specific to your original setup. - Review your concurrency and queue handling code for potential misconfigurations. - Keep Prefect updated to leverage any recent patches or improvements, and consult Prefect's documentation for best practices in concurrency. If the problem remains elusive, sharing detailed error logs or code snippets with the Prefect community or raising an issue might help diagnose whether it's a library bug or a setup issue. Remember, even the happiest of coding setups occasionally stumble upon "quirky" moments!

@Tahir Uddin Khan did you ever find an answer to this? I'm getting the same error

that's just a debug log for when the service that sends logs to the server runs out of logs to send. shouldn't be anything to worry about

good to know Kevin - thanks

Nope, did not find anything around it. Ignored it
