Apache Airflow version

2.5.1

What happened

I'd used airflow 2.3.1 and everything was fine.
Then I decided to move to airflow 2.5.1.
I can't start even webserver, airflow on my laptop consumes the entire memory (32Gb) and OOM killer comes.

I investigated a bit. So it starts with airflow 2.3.4. Only using official docker image (apache/airflow:2.3.4) and only on linux laptop, mac is ok.

Memory leak starts when source code tries to import for example airflow.cli.commands.webserver_command module using airflow.utils.module_loading.import_string.
I dived deeply and found that it happens when "import daemon" is performed.
You can reproduce it with this command: docker run --rm --entrypoint="" apache/airflow:2.3.4 /bin/bash -c "python -c 'import daemon'". Once again, reproducec only on linux (my kernel is 6.1.12).
That's weird considering daemon hasn't been changed since 2018.
