Node.js сервер не освобождает память

У меня проблема с сервером node/express. Сервер работает достаточно хорошо, но со временем использует много памяти. Он начинается с использования памяти около 70 мб. Но тогда для каждого запроса требуется около 2 мб. И вскоре он попадает на отметку 1,5 ГБ и замерзает. Он также не освобождает память во времени. У меня есть общая ошибка на сервере server.js:

    await router.dispatch({ path: req.path, context }, (state, component) => {

      // redirect to another page
      if (state.redirect) {
        res.redirect(state.redirect);
