Downloading after exporting to CSV error

Hi everyone,

I've recently run into this error message: "Failure - will retry later"
when I attempt to download my csv exported data. Any ideas?

I assume you mean when you are attempting to generate the data by clicking
the "Export to CSV" button...

I believe the Export will be re-tried 3 times (I think it re-tries every 10
minutes or so -- been a while since I looked at this code), and then
transition to an Aborted state.

This failure may be an Out Of Memory error.

Once your dataset gets big, the server can no longer generate the CSV file,
as it has to do this entirely in memory and write it out to storage at the
end of the file generation in a single step.

For larger datasets, we recommend either setting up a publisher or using
ODK Briefcase to pull the dataset down to your computer where you can then
use ODK Briefcase to export the CSV to disk (it writes the file one line at
a time, and can handle unlimited dataset sizes).

If you want to confirm the Out-of-Memory error as the cause, you would go
to the Logs tab of the AppEngine console, and choose Version: "background".
You should then see a
/gae/csvGeneratorTask...
entry. Expand it, and scroll down to the red tag in the left column. That
line, or a line nearby, will report a Cause.
