I'm also seeing my app being cycled too quickly.

- What is your application ID?

wicket-gae-template

- How do you know it is being cycled out? You'll need to insert some
code
that only gets called when the app cold starts.

startup is logged in a filter init() method; also logged in a static
initializer just to be sure

- How much time of inactivity does it take before your application is
cycled
out?

a couple of minutes, sometimes less

- What time or days does this seem to happen?

all the time

- What frameworks or libraries are you loading?
