Получение предупреждающих сообщений ниже. Не уверен, что делать. Увидел некоторые из соответствующих должностей с просьбой увеличить количество файловых дескрипторов.Слишком много открытых файлов предупреждение от elasticsearch
Как сделать то же самое?
Даже если я увеличусь сейчас, я столкнусь с той же проблемой при добавлении новых индексов. (в настоящее время работает с 400 индексами, 6 осколков и 1 реплика). Количество индексов, как правило, растет.
