I assume you're using Pacemaker as RedHat Cluster is no longer the default HA solution for RHEL, check the logs at /var/log/cluster for anything related with a failover. As far as I know Pacemaker do several tries to get up the failing resource before marking it as failed.

yes, I am using HA add-on that comes with RHEL 7 which is using pcs and corosync. I am not able to verify if the HA add on does try to restart, since I am not able to shutdown the resource(httpd). – sridhar Sep 23 '15 at 06:35
