Thanks Sabastian and Peter.
After increasing the JVM memory and setting the cache limits the
out-of-memory exception has been arrested. But I started observing lot of
get-token requests failing after sometime i.e after 12hrs of run. On
debugging, lot of failures are observed once the full GC is executed.
Anyone has observed this behavior or any pointers?

Hi Arun,
Yes, we have seen this issue before. A temporary remedy has been to
increase jVM's maximum heap size, among other things, like changing the
eviction rate and infinispan cache sizes.

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.
