"Error R13 (Attach error)" when running "heroku run rake db:migrate"

Hi,

I am trying to migrate my database on my rails app and it is failing. If I look at the logs, I have this:

2013-04-05T08:35:39+00:00 heroku[api]: Starting process with command `bundle exec rake db:migrate` by xxx@dadafish.com
2013-04-05T08:35:50+00:00 heroku[run.6819]: Awaiting client

2013-04-05T08:35:50+00:00 heroku[run.6819]: State changed from starting to up
2013-04-05T08:36:20+00:00 heroku[run.6819]: Error R13 (Attach error) -> Failed to attach to process
2013-04-05T08:36:21+00:00 heroku[run.6819]: Process exited with status 128
2013-04-05T08:36:21+00:00 heroku[run.6819]: State changed from up to complete

The instance is "dadafish.herokuapp.com"

I have trying multiple times and it is still not working.

If I try to get the bash, same:

MacBook-Air-de-Sebastien-Gignoux:dadafish seb$ heroku run bash --app dadafish
Running `bash` attached to terminal... up, run.6041
