Hi Googlers, I was wondering if someone could answer the 3 questions below
regarding slow resource file loading. I am getting a bit tired
of jarring up all classes and resource files (and removing WEB-INF/classes)
every time I want to update my app with GEP.

I have started getting deadlock exceptions thrown from code that uses Guavas
ConcurrentHashMap

Aside from this problem, loading requests frequently seem to block on
something (resource access?). Normally they complete in 5-8 second
I don't see anything that indicates a deadlock. In the logs, I just see
normal deadline exceeded exceptions and stack traces of where it happened to
be when it was cut off. I don't believe I've ever seen a log message with
the deadlock situation.
I thought the explanation might be that non-load
We are using a custom JAR but we see the exceptions.

It is possible that you are running into deadlocks when you set
threadsafe=true. As of a few days ago you should begin seeing stack
traces in your logs if we detect a deadlock at the end of a request.

I see the same behavior on warmup requests but only when threadsafe=true. If
I leave threadsafe set to false, my warmup requests never have deadline
exceeded errors. This is very troubling because we really need
threadsafe=true in light of the new pricing.
I can't find a good explanation for t

I've tried to jar all the classes from WEB-INF/classes folder, but the
exceptions still there. For now I've come to the situation where I have no

We've get the same issue today on our app engine application.
Currently we can see a lot of DeadlineExceededExceptions during the startup
of app engine instances.
Is there any news on how to resolve it?

A ha!!! I have not tested as a jar
How are you deploying your classes? Under WEB-INF/classes, or as a custom
JAR file?

I should add that some loading requests take an excessive amount of time
(20+ seconds) but do not time out. Those are the ones that result in the
unneeded front-end instances shown above.
