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

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.
