django dumpdata hangs

Question

On AWS using Postgres, I do:

manage.py dumpdata

and the server just hangs. Any suggestions about what I should look for?

Answer 1

If you have tons of data, dumpdata will take it's time because it's reformatting everything in JSON (or XML.)

Maybe it even tries to do everything in memory, that might be a problem.

Another tip for these problems where it's hard to pinpoint the root cause, is to add print statements into Django itself.
