[keycloak-user] Uncaught server error: java.lang.OutOfMemoryError: Java heap space

[Arun Velayudhan]

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.
