[appengine-java] Re: Loading requests timeout with DeadlineExceededException while reading classes

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. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java"

How are you deploying your classes? Under WEB-INF/classes, or as a custom JAR file? Another developer posted that they had a massive performance improvement deploying their classes in a JAR file - see https://groups.google.com/d/msg/google-appengine/Gl7OaMOHJD8/i_ti0KceockJ for the relevant t

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? -- You received this message because you are subscribed to the Google Groups "Google App

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

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. On Fri, Sep 9, 2011 at 10:26 AM, Nick Rudnik wrote: > I see the same behavior on warmup request

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

I have started getting deadlock exceptions thrown from code that uses Guavas ConcurrentHashMap http://code.google.com/p/googleappengine/issues/detail?id=5384 Aside from this problem, loading requests frequently seem to block on something (resource access?). Normally they complete in 5-8 second

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. On Wednesday, 31 August 2011 20:15:
