I think your issue might be similar to mine, but I'm not positive. I logged an issue in the GAE Issue Tracker - its been two days without any attention from google. Perhaps multiple comments from users would help escalate it?

Usually at around 5 rps, which hasn't changed. > > For us, since july 15th, these logging.* requests are only logged > occasionally. Instead of the usual 80-100mb of logs of severity 0, we only > get about 15-30mb. The requests are still all logged, but the associated > logging.* data is not. > > In the dashboard, only the requests appear, and when downloading with > severity 0, nothing is being downloaded. > > This seems to happen at certain times.
