My App suddenly returns 500 error

Question

Today, my Application (http://nou-shindan.appspot.com/) returns 500 error. Error logs here but we haven't done any update for more than a year.

Is there a change to the specification of the AppEngine?

What does your application do? Does it change overtime (ie store data, get data from external source, etc.)? — Ryan S

Post your web.xml and then also your entry point servlet, something in your entry servlet is taking longer than 30 seconds which is causing a timeout.
