I've had the same problem. It eventually resolved itself after randomly occurring for weeks. I've made some code changes (which seemed unrelated) so I cannot say for sure if Google made some changes or I did by chance. Do you use transactions in your code? I seem to remember that I had a massive transaction near the end of the handler which I subsequently split into smaller writes and tasks.
It's fairly easy to debug. Just add logging to the last line of the handler (or whatever the equivalent is in Java). In my case the logging occured, but the backend didn't stop, even though there was obviously no code left. My theory was that the backend didn't get the / _ah/stop/ signal for whatever reason. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
