fatal: Unable to create temporary file: No space left on device

Hi
As today we get the following errors on one of our repositories, this is a major blocker for us since we can't deploy our application!

git stdout: /home/www/repo
Fetching origin
remote: Counting objects: 220, done.
remote: Compressing objects: 100% (220/220), done.
fatal: Unable to create temporary file: No space left on device
fatal: index-pack failed
error: Could not fetch origin

Regards
Erik
