Does it try to watch git files? Do I miss something?

Try increasing the max_user_watches for inotify. It is default set to 8192. I bumped it to 100k and things are ok.

cat /proc/sys/fs/inotify/max_user_watches

echo 100000|sudo tee /proc/sys/fs/inotify/max_user_watches

To increase max_user_watches at boot, edit /etc/sysctl.conf and add fs.inotify.max_user_watches=100000 or fix fs.inotify.max_user_watches= to 100000.

Don’t thank me, thank this guy -> http://blog.sorah.jp/2012/01/24/inotify-limitation
