  <p>git version 1.8.3.1
  Jenkins 2.46.2.1-rolling</p>
  
  <p>I tried upgrading git to a higher version but still, it hangs with 1.8.3.1 by following <a href="https://stackoverflow.com/questions/21820715/how-to-install-latest-version-of-git-on-centos-6-x-7-x">How to install latest version of git on CentOS 6.x/7.x</a> link.Giving permissions to /tmp also did not work</p>
  
  <p>My RHEL7 server is from AWS.</p>
