Hi Ikae Can you elaborate on
In the Python runtime, an instance is killed and restarted when a request handler hits DeadlineExceededError. This should fix an issue related to intermittent SystemErrors using Django. http://code.google.com/p/googleappengine/issues/detail?id=772 Is this for any DeadlineExceededError or only uncaught ones ?
