Вопрос:

Я сталкиваюсь с проблемой API » mlock ()». первая загрузка происходит быстро, когда блокируется память из»/sys/устройства/система/узел/узел 0″, но на узле 1 она выполняется слишком медленно, для возврата требуется более 3 секунд. 1637788891.109283 ( 7.153795) set_mempolicy(MPOL_DEFAULT, NULL, 0) = 0 lt;0.000052gt;

кто может помочь проанализировать эти журналы, любая помощь будет признательна. ниже приведена часть следов:
