We had the same problem using Django+nginx+gunicorn. From Gunicorn documentation we have configured the graceful-timeout that made almost no difference. After some testings, we found the solution, the parameter to configure is: timeout (And not graceful timeout). It works like a clock.. So, Do: 1) open the gunicorn configuration file 2) set the TIMEOUT to … Read more
I tried something, and it seems to work. I put preload_app = True in my gunicorn.conf and now the lock seems to be shared. I am still looking into exactly what’s happening here but for now this is good enough, YMMV.
Installing older version of eventlet solved the problem: pip install eventlet==0.30.2 EDIT: you can use the newer versions like this: pip install eventlet==0.33.0 https://github.com/benoitc/gunicorn/archive/refs/heads/master.zip#egg=gunicorn==20.1.0 see: https://github.com/benoitc/gunicorn/pull/2581#issuecomment-994198667 thank you @jmunsch

In the case of gunicorn because it only … Read more
If you do not want to bother with logrotare you can use a full python/gunicorn solution using python logging facilities. Create a file named log.conf with the content below. This will rotate the error log file and access log file daily and will keep the logs for 90 days. Log level is set to INFO. … Read more
A winch signal (or SIGWINCH, short for Signal Window Change) is normally sent to applications when the terminal window size changes, so that applications know to redraw on the screen. However, gunicorn interprets it to shutdown the worker processes, but only when the application is daemonized. Daemonized is just another way of saying an application … Read more
You answered your question yourself here. Though I’ll add my answer in hope that it would help someone else having similar issue. Since your question has 2 parts, of which the first part is solved, ill mark my response for each part: PART 1: No logging happening if instead of directly running the app via … Read more
