При загрузке данных в Neo4j я получаю сообщение об ошибке ниже, и neo4j не работает должным образом.Моя конфигурация памяти - dbms.memory.pagecache.size = 10G dbms.memory.heap.initial_size = 10G dbms.memory.heap.max_size = 30G $ ulimit -n -> 50000 Пожалуйста, помогите мне исправить эту проблему.
Справочная информация: Мы разработали задания talend etl для извлечения данных из таблиц Postgres и загрузки в базу данных Graph neo4j.Во время выполнения этих заданий neo4j выдает ошибку ниже и не работает должным образом.Также он утверждает, что перезапускает приложение neo4j.
Может кто-нибудь столкнуться с этой проблемой и помочь мне в этом?
