django findstatic not looking in every directory

问题

findstatic has a strange behaviour :

1. On localhost

python manage.py findstatic pic/xxx.jpg -v 3 gives me :

Found 'pic/xxx.jpg' here:
  /[...]/myapp/app1/static/pix/xxx.jpg
Looking in the following locations:
  /[...]/myapp/app1/static
  /[...]/myapp/app2/static
  /[...]/myapp/app3/static
  /[...]/env/lib/python3.6/site-packages/django/contrib/admin/static

2. whereas on production

it gives me

Found 'pic/xxx.jpg' here:
  /[...]/myapp/app1/static/pic/xxx.jpg
Looking in the following locations:
  /[...]/myapp/app1/static
  /[...]/myapp/app2/static
  /[...]/env/lib/python3.6/site-packages/django/contrib/admin/static

(note that the 'app3' directory isn't looked into, despite it exists)

Of course, the files located in the 'app3' directory are not found by findstatic, although they exist.

Does someone have any idea where the problem could come from ? (I don't have any special parameter for staticfiles).
