I'm getting this error, even though I'm not running an os.walk or any other kind of file read/write operation with python.
When I'm running
find -L ./ -mindepth 15
I find the files involved in the loop.
Locally is the /usr/bin/X11 and at server I'm getting the following:
error walking file system: OSError [Errno 40] Too many levels of symbolic links: '/dev/fd/6/dev/fd/6/dev/fd/6/dev/fd/6/dev/fd/6/dev/fd/6/dev/fd/6/dev/fd/6/dev/fd/6/dev/fd/6/dev/fd/6/dev/fd/6/dev/fd/6/dev/stderr'
and then from WatchGodReload:

Reloading...
Either I run the container with the volume I usually bind:
UPLOADS_PATH=/var/opt/tmp
LOCAL_UPLOADS_PATH=/var/containers/TEST_UPLOADS
docker build --build-arg POSTGRES_USER --build-arg POSTGRES_PASSWORD --build-arg POSTGRES_SERVER --build-arg POSTGRES_DB --build-arg POSTGRES_PORT --build-arg UPLOADS_PATH --build-arg WHERE_AM_I --build-arg SESSION_SECRET --build-arg DO_YOU_WANT_USERS -t test .
docker run -d --name test_container -v ${LOCAL_UPLOADS_PATH}:${UPLOADS_PATH} -p 7000:7000 test
or without the binding, I still get the same error logs & the app is constantly restarting after every request.
P.S. I've also tried the docker system prune -a, and although there were deprecated stuff, nothing changed.
Much appreciate any suggestions on what to further explore.
The /dev/fd is special pseudo-device filesystem that is showing the VFS handles or simply said the open files of the PID that is examining the device. Trough a coincidence of the build and the running processes in the container, your image has a link to the /dev/fd the same /dev/fd that it's trying to read.
However, this it's not unusual to end in loops if you follow symbolink links on the pseudo-devices, so when using find -L as a super user you should exclude the /dev, /sys and /proc when searching and following links with -xdev
use
find -L ./ -xdev -mindepth 15
