Answer

This error is because of inotify watches reaching the maximum limit in your system.

To check the max number of inotify watches:

cat /proc/sys/fs/inotify/max_user_watches

To set max number of inotify watches

Temporarily:

  • Run sudo sysctl fs.inotify.max_user_watches= with your preferred value at the end.

Permanently:

  • echo 878987 | sudo tee -a /proc/sys/fs/inotify/max_user_watches
