   Hi @tasanuma do you have RBF?
   I don't see this message in my test cluster (we don't have RBF) and wonder if it comes from RBF.
   
   Not familiar with RBF but if each RPC call results in one permission checker object I can see why there are many messages.
   ` /**
      * Get a new permission checker used for making mount table access
      * control. This method will be invoked during each RPC call in router
      * admin server.
      *
      * @return Router permission checker.
      * @throws AccessControlException If the user is not authorized.
      */
     public static RouterPermissionChecker getPermissionChecker()
         throws AccessControlException {
       if (!isPermissionEnabled) {
         return null;
       }
   
       try {
         return new RouterPermissionChecker(routerOwner, superGroup,
             NameNode.getRemoteUser());
       } catch (IOException e) {
         throw new AccessControlException(e);
       }
     }`
