pyinotify yelling no space available

[Mattia Procopio]

don't know why, but in the last days whenever I try to run manage.py runserver I got a pyinotify error, while I'm still able to surf to my pages and work with them I see a nice traceback on console, what's going on?

Traceback:

Sorry if that's obvious, but have you checked that you still have space left on your root partition (or wherever /usr/lib64 is mounted)?

[Mattia Procopio]

yep, I have just 23% used

➜  django git:(django-support-testing) df /usr/lib64

And what does df -i report (​http://serverfault.com/questions/427091/no-space-left-on-device-but-there-is-space#427092)?

What about sysctl -n fs.inotify.max_user_watches? (​https://github.com/seb-m/pyinotify/wiki/Frequently-Asked-Questions)

Shortened the description, we don't need all messages...
