Hello list,
I am seeing an intermittent error that only appears every once in
awhile related to django-livesettings.
Call stack below:
Traceback (most recent call last):

There is a particular condition that is causing livesettings to not
find SHOP as defined, and if I go to www.my_test_site.com/settings it
may or may not error out. It appears to be a race condition of some
sort. Sadly, I cannot reproduce the bug unless I hit it with a high
load. In those situations, I can get a smaller subset of the requests
as errors - and it can happen in any page, but the stack trace is the
same.
I tried different version of django-livesettings. I have tried django-
livesettings-1-4-7 and 1-4-9
Any pointers as to what may cause fetching the settings fail under
high load?
Thanks,
- Ragi
