Check your inotify maximums - this is the system which monitors directory contents and notifies applications of changes. These maximums used to be pretty low, but should be high enough for most users these days. Do you tend to work with multiple directories containing lots of files? See what you get when you run these two commands: sysctl fs.inotify.max_user_watches sysctl fs.inotify.max_user_instances You can increase them temporarily like so and see if it helps: sudo sysctl -w fs.inotify.max_user_watches=524288 sudo sysctl -w fs.inotify.max_user_instances=1024 If it does help, add to /etc/sysctl.conf (or a file in /etc/sysctl.d/).
