AppEngine Java Error code 121 appearing

[YuchTing]

Hi,all

My app (yuchberrysign-hrd.appspot.com) in appengine java had met follow error from 12 hours ago (in console log):

[25/Dec/2013:21:18:53 -0800] "POST /f/login/ HTTP/1.1" 500 0 - "Profile/MIDP-2.0 Configuration/CLDC-1.0" "yuchberrysign-hrd.appspot.com" ms=1313 cpu_ms=160 loading_request=1 exit_code=121 app_engine_release=1.8.8 instance=00c61b117c6db3a9c2acdc57c1279eebd1e6fe

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. This request may thus take longer and use more CPU than a typical request for your application.

A problem was encountered with the process that handled this request, causing it to exit. This is likely to cause a new process to be used for the next request to your application. (Error code 121)

This app has been running normal for many time(about 1 year).

I've searched many time(here & here) for this error and restarted the instance of appengine java many time and changed back version before about 112 days ago, but it's always appearing.

It seems internal error in appengine and it will gone after a moment...

I found hash string of instance is NOT my app's instance in appengine console,when I click the url link in log to redirect console, it say:

Could not find specified instance with key 00c61b117c15f841324d4d7bbce96c77aa110e

Is there some method to solve this problem or other useful information to tell me ?

Please help me, thanks.

That's exactly correct. Error 121 is an App Engine internal error, your application did nothing wrong. If you see these errors repeatedly though, you can try forcing your app to move to different machines by changing the frontend instance class to a higher class (more RAM/CPU) then back to the original class size: https://developers.google.com/appengine/docs/adminconsole/performancesettings#Setting_the_Frontend_Instance_Class

Thanks for your reply. After wait for about 10 hours, the error had gone itself . I shutdown instance of appengine many times before it , but it was useless .

If I meet same error again, I will use your advice to repair it, thank you a lot.
