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 -
Try java.util.logging.Logger.log(Level level, String msg, Throwable
thrown)

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?

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
