I used uwsgi to start my project, and then I logged it in my uwsgi configuration, and then I logged it in my django project setup file, but I found out today that my django log only logged this morning from 9:00 to 10:00, and all subsequent logs were missing. But in it’s in uwsgi log file, Why?

my uwsgi.ini

    },
}

my django version : 3.2.3

python version: 3.6.13

My guess is that the multiple processes are causing file handle contention issues, so the logs aren’t written to django’s log files?

I want to know why this happens?
