Nhận các thông báo cảnh báo dưới đây liên tục. Không chắc nên làm gì. Đã thấy một số bài đăng có liên quan yêu cầu tăng số lượng mô tả tệp.Quá nhiều cảnh báo tệp mở từ elasticsearch
Làm cách nào để thực hiện tương tự?
Thậm chí nếu tôi tăng ngay bây giờ, tôi có gặp vấn đề tương tự khi thêm các chỉ mục mới hay không. (hiện đang làm việc với khoảng 400 chỉ mục, 6 mảnh và 1 bản sao). Số lượng chỉ số có xu hướng tăng thêm.

Đây không phải là cảnh báo. Đó là một lỗi. Bạn không thể mở tệp. – EJP
