Now that RHGS 3.4 Batch Update 4 is out (https://mojo.redhat.com/docs/DOC-930684), would like the customer to upgrade to get out of this situation.
Comment 5 Amar Tumballi 2019-03-28 06:40:40 UTC 
Adding this as depends on bz#1511779, and marking as CLOSED WORKSFORME..


Please ask customers to upgrade to avail the major memory usage related feature.
