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

[Stian Thorgersen]

Could be https://issues.jboss.org/browse/KEYCLOAK-3202 if so it's not fixed
in 1.9.8. There's a work around though, you can set "<eviction
max-entries="10000" strategy="LRU"/>" for the realmVersions cache. Also,
make sure you have a sane max entries on the users cache.
