Unable to start artifactory on RHEL 7.6. Fails with error Unable to start service artifactory: Job for artifactory.service failed because a configured resource limit was exceeded

I am trying to setup a new Artifactory instance on RHEL 7.6. While running the ansible role for installation, after installation it fails to start the service

Job for artifactory.service failed because a configured resource limit was exceeded. See "systemctl status artifactory.service" and "journalctl -xe" for details

systemd[1]: Can't open PID file /opt/jfrog/artifactory/run/artifactory.pid (yet?) after start: No such file or directory
systemd[1]: Failed to start Setup Systemd script for Artifactory in Tomcat Servlet Engine.
systemd[1]: Unit artifactory.service entered failed state.
systemd[1]: artifactory.service failed.

Found one article https://www.jfrog.com/jira/browse/RTFACT-18009, where it talks about reinstalling in a different directory and editing certain config files for env variables and also changing of links etc. I didnot want to attempt all this, as i want to setup a clean install for a production environment.
