@microhuang, can you explain how we can reproduce the issue? Without reproduction steps or more explanations, we won't know how to help with this. |

I can't reproduce this problem. It sometimes happens (it's a low-frequency phenomenon) and sometimes it doesn't happen. I don't understand the reason. |

Converted it to discussion until we at least get some clue where it can come from. Can you provide more information - i.e. logs from the webserver, when it happens, what happens if you get it "successfully" rendered wihout recursion what kind of log/task information you see when you succeed? IT seems to mee that you have somewhere a complex jinja template which causes inifinite recursion. - almost as if you embedded the '{% include %}` in one of your jinja templates that cause jinja to recursively load the same file. Could you please extract any non-standard/suspicious jinja directives you use in your configuration/files/DAGs? |

It's you that should solve your problem, but what your problem is, hard to say without you explaining what you do and what stack trace you have. I recommend you to show your error and explain circumstances in a separate discussion, where you explain your stack trace etc. And then you will maybe have a chance that someone will help to solve your problem. |

Something bad has happened.
Airflow is used by many users, and it is very likely that others had similar problems and you can easily find
a solution to your problem.
Consider following these steps:
gather the relevant information (detailed logs with errors, reproduction steps, details of your deployment)
find similar issues using:
if you run Airflow on a Managed Service, consider opening an issue using the service support channels
if you tried and have difficulty with diagnosing and fixing the problem yourself, consider creating a bug report.
Make sure however, to include all relevant details and results of your investigation so far.
