[appengine-java] Re: Application restart for almost every request? What happened?
I think this is more supportive of not being able to use GAE for anything casual :) Serious applications don't seem to suffer from this problem.

This is really one of the core problems why you cannot use GAE for anything serious. Even if you get enough traffic, some users suffer from instance recycling every second (read the comments at the issue). -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

There is no real workaround, since they are cycling your application out since it's getting such low traffic as explained in the FAQ. The best you can do is minimise the loading time, by removing dependencies on complicated frameworks and using lazy initialisation. As soon as your application starts getting a more consistent amount of traffic the problem will be minimised, although you will still get some loading requests as the GAE backend potentially load balances your application.

OK, I did that. But is there any workaround or some other way to avoid this, I am sure that my app is run with low resource requirement, it indeed have no reason to restart, but currently it restarts almost in every incoming request!

Hey, Actually, what you probably want to do is star this issue: http://code.google.com/p/googleappengine/issues/detail?id=2931 It's been happening for awhile now, but generally only to low-traffic users, so it hasn't gotten much attention. Creeping up in the list, though!

You probably want to have a read of the following FAQ - http://code.google.com/appengine/kb/java.html#What_Is_A_Loading_Request On Jun 29, 4:13 am, opok wrote: > Error Message: "This request caused a new process to be started for > your application, and thus caused your application code to be loaded > for the first time.
