Increase the number of files git can track
Have you worked on such a large project that git refuses to track them all?
Try increasing your max system watches!
This solution consumes more ram, so do more investigation before implementing if you are running in a low ram environment.
sudo sh -c "echo 'fs.inotify.max_user_watches=524288' >> /etc/sysctl.conf" sudo sysctl -p
