@Marvin i am running a prefect flow from a celery task in my django project. but the flow sometime crashed midway saying "Crash detected! Execution was cancelled by the runtime environment.". what can be the reason

Ah, your flow is going kablooey midway. Let's find out why! 🧐 Could you tell me which version of Prefect you're using? There are two major versions, 2.x and 3.x, and the docs for each might have different info.

@Marvin i am using version 2.x

It looks like the issue "Crash detected! Execution was cancelled by the runtime environment" has been discussed a lot. Some key insights include: 1. HTTP Errors and Timeouts: Sometimes, the crash is due to server errors or timeouts, especially on tasks that take longer to run. 2. Docker Issues: Long-running containers can cause the environment to cancel tasks if they don't terminate properly. 3. Concurrency and Execution Contexts: Using

asyncio

or process pools with incorrect configuration can lead to crashes. It's essential to ensure that you set the appropriate context (e.g., using

spawn

instead of

fork

on certain systems like Linux). Check out some related issues: - GitHub Issue 14984 - GitHub Issue 7560 - GitHub Issue 9229 Potential solutions include: - Ensure you handle long-running tasks properly and set appropriate timeouts. - Review how you configure Docker containers for task execution. - Adjust concurrency settings and context handling in your code. This should help debug and potentially fix the crash issues in your Prefect flows! 🚀
