I keep receiving this intermittent error even with just the poll application. My application is fairly simple, where at least for the moment, it is just serving up a small csv file via JSON to a jquery table. Both the traceback and my system configuration is listed below. Thanks in advance!

I'm deploying a django app made with django channels using nginx, gunicorn and daphne. During deployment when I run python manage.py makemigrations, I get the following error. Could it be because the python version on my local machine was 3.7 and on remote ubuntu server is 3.5?

Any ideas what might be causing this?
It's an operating system error. The maximum number of open files is limited. Try to find where you open files and forget to close them.
Open less file descriptors at once.
set(open(filename) for filename in new_filenames)
is where the error occurs.
When i run the tests on my local machine everything works fine
when i run only my apps tests everything works
but when i run the full set of tests in jenkins it fails,
and the even stranger thing is all the tests pass.
Im guessing it has something to do with pylint, but im not sure.
Would greatly appreciate any suggestions on whats happening?
+ python nexus7/manage.py jenkins

Need some help starting up the djangoappengine testapp.I followed the instructions at http://www.allbuttonspressed.com/projects/djangoappengine, but when I run ./manage.py runserver . while in the project directory I get the following error:

Anyone experienced this issue ?
You probably already solved this, but for future users:
The warning can have multiple causes:
data store is empty, in that case ignore
wrong permissions on the datastore files
data corruption issue
The error can be solved by updating djangoappengine
Update to the latest version of google app engine.

Steps I would take would be
Run the dev server on your Media Template instance. If that runs successfully, it obviously is an error with your apache/nginx/whaever setup.
I dont have experience running apps as FCGI, which it looks to em you are trying to do. It looks to me that somehow when Fcgi runs, it is unable to find your apps. So this is possibly a PYTHONPATH issue. Log/Print sys.path from your fcgi script and look there.
