Help, I changed nothing but my application ate all my resources

[Tony]

Now it says "Your application is at or near its daily budget limit." It just stopped serving. And during all day it was flooding me with errors like:

1. 2012-03-09 09:55:08.090

3. I 2012-03-09 09:55:09.391

   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.

4. W 2012-03-09 09:55:09.391

   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. If you see this message frequently, you may be throwing exceptions during the initialization of your application. (Error code 104)

And now I'm out of money. What's happening? It can't be my fault, why I'm paying for this?


App ID: crystalupdate

Indeed, appengine was having a problem and some apps ended up chewing up quite a bit of instance time in order to fail with the sort of error your app encountered.
