```

Also observed the confd-notifications restart by throwing this error

```auto
confd_notifications: confd_notifications.c:112: handle_diff_notif: Assertion `(maapi_diff_iterate(maapi_socket, tctx->thandle, iter, ITER_WANT_ATTR, ((void *)0))) == CONFD_OK' failed.

```

Can anyone please help to understand what this error means?
