[keycloak-user] Out of memory error on Keycloak cluster

[Bill Burke]

I believe we fixed some cache leakage problems sometime between 1.9.1 
and 1.9.8.  You'll have to search JIRA.  I strongly suggest you upgrade 
to 1.9.8.  We did a huge amount of stability, performance, and bug fixes 
between 1.9.1 and 1.9.8 to get Keycloak ready for product.  RH-SSO is 
based on Keycloak 1.9.8.
