This is happening to me in a Groovy on Grails application, but it
doesn't seem to be a loading problem. Even if I'm clicking through
the application I get these kinds of problems randomly. Probably one
out of every five clicks fails if I wait for it to. Grails uses
Spring underneath so maybe thi
Now I get this 500 error quite frequently. See the log below in Admin
Console. I believe this is different from HardDeadlineExceededError
problem (exceeded 30 seconds limit) as there wasn't any
HardDeadlineExceededError exception logged in log. The site was
accessed by one user, hence the simult

I am not sure what do you mean by action class. Could you please give
me a pointer?
I made change to ping a Controller class every 1 min. Same problem
persists.

maybe you'd better run hitting an action class, not a simple jsp page.

I used to run cron to make request every 1 min to a jsp which only
write out a line of text. I uses a HttpSessionListener to listen for
any "loading request"/startup. Even ping every 1 min the loading
request still happens. I still got 500 error due to the request CPU is
is over the limit.

Can anyone confirm that Spring MVC version 2.5.6 is working fine on
GAE?
No, the same problem is also in spring2.5
there is no better way to avoid that, you can try to run cron job to make
your application reactive .
Hitting a url every 1 miute, i did this ,that's all i did.

This problem normally happens "In the case of loading requests,
though, the execution time is artificially longer due to the extra
application initialization required.".

Okay, the first thing mentioned was that you are using Spring. We are
doing an experiment removing Spring in our app to see what impact it
has on startup time.

No, the 30 second limit is a hard limit. If a request can't finish in
30 seconds (or somewhat earlier), you get an exception. You then have
an undetermined amount of time before the app engine kills your
request and returns a 500 status code. You wouldn't happen to be using
Spring, would you?

Hi Wong, I had this problem a while back when I was doing some
intensive computations in my code. Eventually the entire app would
become blocked for some minutes. The limit for API CPU is a lot
higher than for CPU usage in your own code. I didn't come up with a
solution to the problem -
I enable billing the set the quota to 3 times over the free quota for
CPU Time. However, sometimes the request still fails with HTTP 500
error after app is being cycled out and "loading request" is being
performed.
In the log I see the following message:
This request used a high amount of CPU, a
