You get this message when you app is still starting while other
requests come in. The only current solution is to reduce start up
time - pinging is not a satisfactory solution because you still get
frequent "loading requests". With Guice I was able to reduce star up
by using a non AOP version which did no bytecode enhancement. Also,
try delaying initialising components until they are needed.

This is a big problem for any applications using Springframework,
which has startup time about 20 seconds.
Here is corresponding entry from the log file for one of the
executions of such scheduled task.

Request was aborted after waiting too long to attempt to service
your request. Most likely, this indicates that you have reached your
simultaneous dynamic request limit. This is almost always due to
excessively high latency in your app. Please see
http://code.google.com/appengine/docs/quotas.html for more details.

Can you please advise what could be done in such and if I am missing
anything obvious?
Thanks
