Hello, I developed an app with GAE/J and I created a cron job like this:
<?xml version="1.0" encoding="UTF-8"?>
<cronentries>
<cron>
<url>/cron/v1/cleanDB</url>
<description>Clean Data Base</description>
<schedule>every day 04:00</schedule>
<target>clean-db</target>
</cron>
</cronentries>
Also, I defined this backend:
<backends>
<backend name="clean-db">
<class>B1</class>
<options>
<dynamic>true</dynamic>
</options>
</backend>
</backends>
My cron job and backend are always working fine, but one day when the crob
job was woken and the backend must have started, It consumed 46858162ms
(13h) and I received this error:
2013-01-05 18:01:00.669 /_ah/start 500 46858162ms 0kb instance=0

took too long to shutdown.
Then, I received multiples errors every 200ms:

This error consumes my free 9h of backends (I do not allow even billing)
Well, what was the problem? Maybe it was a causal problem, but I am very
disappointed
with GAE, though I have enabled billing, how much would it cost?
Is there any way to prevent this kind of thing?
Thanks
