Error: ENOSPC: System limit for number of file watchers reached, watch

Linux uses inotify to monitor file changes. This error is due to the file watchers being reached.

In most cases, restarting the dev-server will fix this issue.

If you want a permanent solution, you can increase the maximum number of file watchers.

# check current number
$ cat /proc/sys/fs/inotify/max_user_watches

# set a greater value
$ echo fs.inotify.max_user_watches=<increased-value> | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
