AppEngine Application Problem

When I attempt to upload my large form to Google App Engine/ODK Aggregate I
get the subject error message (whole error message listed at bottom of this
note).

The form appears to be uploaded but missing the 4 media attachments. I say
it "seems" only because I can click and see the xml. When I deselect the
"downloadable" check box I see another error... "Error: Form definition
incomplete or missing"

I followed the instructions given in the subject error message...

  1. I made my account a paid account and gave it some budget. No help!

  2. I checked the log has a warning or two per section ... and this ONE
    Critical message...
    Uncaught exception from servlet
    com.google.apphosting.api.DeadlineExceededException: This request
    (30ee352e6b3506b7) started at 2013/11/19 21:27:31.52

  3. I tried reducing my questions in my survey from 1742 to 50. No help!

  4. Reduced my questions to 1. It worked!

All my questions are basically the exact same format and lengths. So I
think it is a performance issue with the size of the form. Although this
form size worked on FormHub.

I tried boosting the server performance.
I raised to these parameters...
Fronted Instance Class: F4-1G
Memcache Service: dedicated 5GB
No Help!

What else should I try??

Thanks!

··· ---------------------------------------------------------- AppEngine Application Problem A problem has occurred that prevents your AppEngine application from responding. Your application may have exceeded its per-minute or daily usage quotas.

Please visit your application dashboard at Google AppEngine. The Billing
Status section will indicate what daily or per-minute usage limits your
application has exceeded.

If your application's usage limits have not been exceeded, then look for
performance issues within Google AppEngine cloud services. From your
application dashboard, click on the theSystem Status link on the left
sidebar under the Resources heading. This will report problems with Google
AppEngine cloud services.

If neither of those indicate any problems, then your application's Logs
may; these are reachable from the dashboard via the Logs link on the left
sidebar under the Main heading.

First, have you upgraded your ODK Aggregate to the latest 1.4 release? If
not, do so. See
http://code.google.com/p/opendatakit/wiki/AggregateReleaseNotes for upgrade
information.

Second, download ODK Validate
http://code.google.com/p/opendatakit/downloads/detail?name=ODK%20Validate%201.4%20for%20ODK%20Collect%20v1.4%20rev%201037%20and%20older.jar

Use that to verify that your form (the XML file) does not contain errors.

The generic error that ODK Aggregate reports ( AppEngine Application Problem )
is unfortunately a restriction on AppEngine and our server implementation
-- it is difficult to report specific detailed error messages to the user,
and the reported error, once you understand how to use the system, is the
most likely cause of a problem.

For very large forms, there have been several problems with the
table-splitting logic in earlier ODK Aggregate releases. These could cause
infinite loops, and you may have a form definition that causes this problem
to occur. If you still cannot load the form using the latest 1.4 release,
please send me the form directly ( mitchellsundt@gmail.com ) and I will
take a look at what is going on within ODK Aggregate.

Thanks Mitch!

I sent you the form. I am using the latest install of ODK Aggregate and
the validate was clean.
