Hi François, The basic rule to determine a need for a new instance is described here: http://stackoverflow.com/questions/11525717/when-does-the-app-engine-scheduler-use-a-new-thread-vs-a-new-instance
Other than that, there can be some rare-case scenarios where the scheduler need to spawn a new instance due to some transient issues within the underlying infrastructure, which are not surfaced to developers, and handled automatically by the scheduler. I think it's a nature of a distributed and shared system like App Engine. I assume you already have starred the following issues, but please star them if you haven't. https://code.google.com/p/googleappengine/issues/detail?id=7865 https://code.google.com/p/googleappengine/issues/detail?id=5858 On Tue, Jan 22, 2013 at 3:22 AM, Francois Masurel <[email protected]>wrote: > Could someone from Google explain why a new dynamic instance was started > though an existing one was still alive a served only 1 request for the last > 15 minutes ? > > > <https://lh5.googleusercontent.com/-jKN7PFnKKSE/UP51xcWhoOI/AAAAAAAA0FA/keeSdM_yyDM/s1600/Instances+-+VinoCities+-+Google+Chrome.jpg> > Really looks like a waste of resources (and money). > > Thanx for your answer. > > François > > -- > You received this message because you are subscribed to the Google Groups > "Google App Engine" group. > To view this discussion on the web visit > https://groups.google.com/d/msg/google-appengine/-/wZs7GyY8z1sJ. > To post to this group, send email to [email protected]. > To unsubscribe from this group, send email to > [email protected]. > For more options, visit this group at > http://groups.google.com/group/google-appengine?hl=en. > -- Takashi Matsuo | Developers Advocate | [email protected] -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
