Hey Arun,
Since Keycloak uses Infinispan as a cache, and Infinispan stores everything
on-heap, my lucky guess is that Xmx is simply too low (I would also advice
removing Metaspace calibration parameters for now).
If you wish to diagnose this further, these are the steps you might perform:
1) Turn GC Logging on:
http://www.oracle.com/technetwork/articles/java/gcportal-136937.html
2) Check Infinispan JMX statistics:
http://docs.jboss.org/infinispan/8.2/apidocs/jmxComponents.html#CacheCont...
(you
will be mostly interested in number of entries in individual caches)
Thanks,
Sebastian

Hello,
We ran keycloak with some basic load (like auth, gettoken) for few hours at
theand after sometime Keycloak threw an Out-of-memory error. Has anyone
faced similar kind of problem. Would be keen to know what was done to
mitigate.
Version of Keycloak -> 4.0.0.Final.
