Я использую пример, предоставленный официальной аккой: https://github.com/akka/akka-samples/tree/2.5/akka-sample-cluster-scala.
Моя ОС: Linux Mint 19 с последним ядром.
А для Worker Dial-in Example (Transformation Example) я не могу полностью запустить этот пример, так как в / dev / shm недостаточно места. Хотя у меня есть более 2 ГБ свободного места.
Проблема в том, что когда я запускаю первый интерфейсный узел, он потребляет пространство в несколько килобайт. Когда я запускаю второй, он съедает несколько мегабайт памяти. Когда я запускаю третий, он занимает несколько сотен мегабайт памяти. Кроме того, я просто не могу запустить четвертый, он просто выдает ошибку, которая вызывает сбой всего кластера:

Кажется, он посылает огромное сообщение (48MB+?) на все узлы.
Так что здесь? В чем основная причина и как мне это исправить?
