Thanks for the tip, but waiting does not help. I reinstalled 1.6.3 and now it's working again. Maybe It was not clear enough but this happens every time the server is shutdown(not only reboot).
I hope it will be fixed in the next release. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
