We are working on enhancements that will hopefully reduce this
initialization time for cold instances, which should be rolled out with the
next couple of releases. There are several other threads on this, and we
definitely recognize the importance and appreciate your patience.
Regarding the first post, if your file is so large that it takes 80 seconds
to load it into the development server, I suggest re-structuring your
application to remove this dependency. Even with the planned enhancements,
it's unlikely that you'll be able to load such the complete file into main
memory without hitting the 30 second deadline or triggering an out-of-memory
exception.

Yeah,
AppEngine drops your request after 30 seconds.
My app takes 20 seconds to initialize in development, and half of the
times it will finish loading within 30 seconds. Other times it goes
pass 30 seconds and gets the same 500 error like yours.
Google needs to make an exception for the initial cold boot timeout.

Hi,
I am working with my friend to build an app (hoogentia.appspot.com)
which
requires loading some learned model files to memory. I have a startup
servlet that does this (loading model files to memory). Since it needs
more
mem, I run this app in dev mode with memory setting of -Xms1024m
-Xmx2048m. I
dont have any issues in development but when i deploy it to app engine
and
access my application, the startup servlet is invoked and it comes up
with
an Error 500. I am not getting any useful info from the logs. I am
assuming
the issue is with jvm settings for app engine in production. I looked at
this thread (
http://groups.google.com/group/google-appengine-java/browse_thread/th...)
and modified appcfg.sh to
java -Xmx2000m -cp $SDK_LIB/appengine-tools-api.jar \
com.google.appengine.tools.admin.AppCfg $*
After doing an update, I still get the 500 Error.
In dev mode, it takes like 80 seconds for the model to get loaded in
memory.
Any thoughts / help / suggestions greatly appreciated,
thanks
Joe.
