Re: [appengine-java] Re: After how much time of no traffic does GAE shut-down the instance
the other talk about your problem!https://groups.google.com/group/google-appengine-java/msg/2c425aa60b091f5d?dmode=print GROUPS Title: App instance recycling and response times - is there solution? https://groups.google.com/group/google-appengine-java/browse_thread/thread/bd5110b72b852e15/9f751301a9fb943c?q=App+instance+recycling+and+response+times+-+is+there+solution#9f751301a9fb943c 2010/1/15 Ikai L (Google) ika...@google.com Hey everybody, 2 minutes is EXTREMELY aggressive. If you have evidence that your app is being cycled out this quickly, can you let us know your app ID? There may be something going on with your application. Our numbers indicate that even if you are getting a minute amount of traffic, you shouldn't not be cycled out. In general we discourage using cron to ping your application. Cold startup time is a very high priority for us. 2010/1/10 杨浩 skzr@gmail.com my GAE app too shutdown every tow minutes when no request! so when my app init that is terrible, because spring init need 15s! so my answer is: create a cron:every one minutes to run once,It's work very good!(every tow minutes don't keep my app online, It's still shutdown!) -- Ikai Lan Developer Programs Engineer, Google App Engine -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

It's been some discussion about this topic. You may want to seek posts with words keep warm or cold start, for instance.
