Quota error on fresh account

[Chris Laux]

Hi all,

I set up the demo as it comes from the subversion repository and ran
it, but run into quota errors. But I'm using a brand new application
with empty quotas and the Dashboard shows that everything is below 5%!
Is this normal? What is it caused by? Error messages are below...

Thanks,
Chris

Yeah, those are the quota errors that I ran into most frequently.  There's an undocumented "database work" quota that you can pretty easily run into.  Letting your driver sleep for about 30 seconds or a minute, and keeping only 2 or 3 requests inflight is how I've resolved it.

This is just something we have to accept until AppEngine allows us to purchase more quota.
