[keycloak-user] Get token returns new refresh token before expiry of refresh token

Hello All, Whenever we renew an access token keycloak returns a new refresh token. Suppose the access token expiry is 30min and refresh token is 24hrs, for every new access token request (i.e intervals of 30min) a new refresh token (same expiry) gets created by keycloak. I am suspecting if this might be a cause for memory growth in keycloak under traffic conditions. Any specific configuration that can be enabled in keycloak so that keycloak can reuse the same refresh token till it expires. Arun
