You get this error when your request waits in a pending queue. App Engine apps are autoscaled IF they can average under 1000ms. If they cannot, we do not give you additional instances, and requests line up in a pending queue. If your request waits in the pending queue for more than N seconds (I think N is 9 at the moment but I don't know for sure off the top of my head), this message is returned.
You'll need to look at the average latency and figure out how to drop it to under 1000ms. Alternatively, if you enable concurrent Java requests, it'll be a higher ceiling before this error appears if you have "Always On" since you can serve a total of 3 (always on instances) * M (concurrency factor, I think this is 40 at the moment) requests at one time without requiring autoscaling.
