Hi Jeff,

Setting Idle instances to automatic, as Johan Euphrosine suggested, seems
to have solved the problem, at least temporarily (I was at 1 minimum and 1
maximum before).
I'm just a bit
in the pending queue - why is GAE shunting new requests to
instances with an effective 10-20s wait time instead?

You are supposed to have something like this in your application web.xml :
servlet-mapping
servlet-nameproviderServlet/servlet-name
url-pattern/authenticate/url-pattern
/servlet-mapping
In fact, it seems that my browser blocked the openid url for some security
reasons related to being in an iframe.
I just had to open this url in a new tab to solve the problem.

I've successfully built an OpenId provider on GAE Java using this project

I would also like to have more detailled information about memory usage in

The memory counter keeps increasing constantly for one of my app (vncts1).
It looks like I'm being hit by a memory leak.
But when I profile my app locally on the dev server, there is no such

Hi Don,
I was just wondering : could these buggy DeadlineExceededExceptions cause a

I've seen my instance take up to 134MB just running 2 simple datastore

Hi everybody,
I would like to know how much memory space do your Java instances use.
Mines use from 75 to 90 MB of memory on average basis.

Actually there is a problem is you store content keys as string in the
datastore.
They can't be imported back in another application because keys are
application prefixed.

Each app instance runs in its own JVM. So it should be safe to cache

It looks like you can delay tasks via API :

Set the number of milliseconds delay before execution of the
