Re: [google-appengine] Re: Urgent, Need Help: Instances are shutting down after a couple minutes of inactivity.
I'm experiencing this problem as well and can not demo my app. app id: gobandpass For me each request is starting a new instance thus causing long response times. I am in development and therefore the only person on the app. So I can clearly see for each client request a new instance is being started. Performance settings are (and always have been) automatic, automatic for both instance and latency which always seemed to work fine until now. Note, timing wise, I deployed an app on 12/13 and everything tested out fine. Then on 1/8 I deployed again and now have this problem. In between these dates I was working locally and therefore would not notice exactly when this problem cropped up. Somewhere between 12/3 and 1/8.

Also FYI, this whole issue could be resolved if you would stop sending user facing requests to cold uninitialized instances in java GAE. Handling user requests in ways that you know will cause 20+ second response times is pathological. All new development for us on GAE is blocked until this issue can be resolved.

By the way, if anyone interested has not starred the relevant issue in the issue tracker, please do so! https://code.google.com/p/googleappengine/issues/detail?id=7865 On Monday, December 17, 2012 10:32:40 AM UTC-5, Cesium wrote: On Dec 16, something changed. Now, instances do not survive more than a couple minutes of inactivity (no incoming requests). Thus, low traffic applications see long latency since a new instance is created for the request. This is disastrous for my application (and customers). Can someone please help? Thanks, David -- You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Re: Urgent, Need Help: Instances are shutting down after a couple minutes of inactivity.
I have the same problem. We need to migrate away from Java on GAE, I fear it will *never* work right with long instance spinup times. Google gets their instance scheduler half-way working, then make some breaking change that crushes the user experience for low traffic applications.

What chaps my hide is the unannounced CHANGE in the behavior (for my app). I have been running for months with a single instance and no problems. Then, it breaks. No warning. No feedback. No drinks. No dinner. Nada. I have stayed out of the discussion because all was well. Oh, and, Takashi, don't bother this time. I have designed a non-appengine solution. -- You received this message because you are subscribed to the Google Groups Google App Engine group.

I hate when my hide gets chapped. And drinks would help... Good luck out there.

Yep you're right, adding some more resident instances doesn't fix the problem, the scheduler is definitively broken. Feeling desperate.

[google-appengine] Re: Urgent, Need Help: Instances are shutting down after a couple minutes of inactivity.
I should add code so that whenever an instance spins up to a URL that is not a warmup, it sends an email to the GAE devs. Perhaps I will try it on a free app first, just to get the kinks out... ;) On Monday, December 17, 2012 7:32:40 AM UTC-8, Cesium wrote: On Dec 16, something changed.

I fear that Sir Brandon has given us a fair assesment of GAE and GAE support. The unicorns have left the building.
