I am using ubuntu 18.04 LTS . For react-native all setup are done(installed watchman) , but still while i am running the react-native start command , it take 100% cpu utilization and after some 2-3 minute the process got killed and then the cpu utilization got normal .
Every time while i run react-native start command for the 1st time . It showing some watchman error and then i follow this link Error when running watchman.
After that while running the command again it agin take 100% cpu utilization and process got killed
