Lots of steady errors here. No, I don't use DJango.
It does seem to be more likely on a cold instance, but probably because there is more actions that can potentially fail in such a case. The logs simply show everything is just taking way too long. It's like it's running in slow motion.

It frankly has nothing at all to do with the code, it's a problem with App Engine. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
