Hi! I had the same problem with very high latencies and DeadlineExceededErrors. I don't know if you have the same problem as I did but I hope this helps for some of you.
I'm using django 1.0.2 with zip import. So I just updated my google- app-engine-django helper library and the latencies are now gone. :) Best regards, Taro On Sep 19, 2:17 am, Michael <[email protected]> wrote: > I'm having the same problem (app: sovpad) > > Except from my logs can be found > here:http://groups.google.com/group/google-appengine-python/browse_thread/... > > On Sep 19, 1:05 am, bvelasquez <[email protected]> wrote: > > > I'm experiencing this also (app: jacob-6). 2 Sept. is when I started > > noticing the issue.
