Does appengine have a new limitation on “Exceeded maximum allocated IDs”?

问题

My app is running fine for months. Today it starts to give error on "Exceeded maximum allocated IDs" with datastore put. Is this something new with appengine quota and limitation?

While we're unsure how you ended up with such large ids, we are taking steps to accommodate them.

You can track this on https://code.google.com/p/googleappengine/issues/detail?id=9118.

Thanks.

Our app had the same problem.

There is not such a limit (quota). It seems that at some point the ID generate for some entities is to high and this exception is thrown.

As a solution/workaround you can generate your own IDs.
