[SOLVED] Error when running watchman

Issue

When I run react-native start, I am getting the following message

Error: A non-recoverable condition has triggered. Watchman needs your help!
The triggering condition was at timestamp=1489123194: inotify-add-watch(/var/www/html/eventManager/android/app/src/main/res/mipmap-mdpi) -> The user limit on the total number of inotify watches was reached; increase the fs.inotify.max_user_watches sysctl
All requests will continue to fail with this message until you resolve
the underlying problem. You will find more information on fixing this at

Solution

echo 256 | sudo tee -a /proc/sys/fs/inotify/max_user_instances
echo 32768 | sudo tee -a /proc/sys/fs/inotify/max_queued_events
echo 65536 | sudo tee -a /proc/sys/fs/inotify/max_user_watches
echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf
sudo sysctl -p

watchman shutdown-server

This one helped
