Ошибка при параллельном расчете в версии 19.4

Доброго времени суток. Надеюсь, кто-нибудь подскажет, в чем может быть проблема. Есть кластер из 3 компов, настроен RSM. Запускаю параллельный расчет, на все компы распределяется нагрузка, но через пару минут выпадает ошибка. Может кто сталкивался, в чем проблема?
