Понятия не имею, как исправить ..
На скриншоте видно, что вы используете Munin v. 1.4.5. Очень старая версия. Я использую 2.x.x, и у меня нет плагина мембюсер. Возможно проблема в этом плагине с неверными определениями. Я вижу какую-то версию этого плагина по URL: http://munin-monitoring.org/browser/munin-contrib/plugins/system/membyuser
Но я рекомендую вам обновить munin, потому что старые версии очень глючны.
