Hi @ALAKA_BHATTACHARYA ,
Welcome to SonarSource Community! 
What version of SonarQube are you using?
Please check your log files and see if you have any other errors that stand out. Please see https://docs.sonarqube.org/latest/instance-administration/system-info/ for more information.
Also, please ensure you’re not running sonarqube as root, which we discuss here in Operating the server documentation:
On a Unix system using SystemD, you can install SonarQube as a service. You cannot run SonarQube as
rootin 'nix systems. Ideally, you will have created a new account dedicated to the purpose of running SonarQube.
Make sure that all of the files in the directory for SonarQube are owned by the user you are logged in as.
Please review this other post that may help you: SonarQube fails to start in console
