Hi! I've had some problems with flows getting stuck after all tasks are finished and did not receive support so I've tried to recreate a minimal reproduceable example see code below. What is happening for me: The tasks can run fine, but after the tasks completes the memory usage explodes (goes to 100%). Depending on the size of the data the flow will either: • get stuck after last finished task • finish succesfully • either of above intermittently I can run the same flow perfectly fine in Prefect 1, it also runs a lot faster even when increasing data a lot. I attach a log of a unsuccesful prefect 2 run in the thread:

Hi Andreas. Sorry to hear about the issue. I consulted with our folks internally and we don’t have a quick fix. Are you able to file as an issue at https://github.com/PrefectHQ/prefect/issues?

Sure
