You can get your current inotify file watch limit by executing: (it's usually 8K)
$> cat /proc/sys/fs/inotify/max_user_watches
or
$> sysctl fs.inotify
You can increase the limit with this command
$> echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sysctl -p $> echo fs.inotify.max_user_instances=512 | sudo tee -a /etc/sysctl.conf && sysctl -p
