Gửi các bạn,
Server của mình mấy hôm nay tải rất cao lên đến hơn 50%. Nhiều lúc mình không thể kết nối FTP đc và SSH đc, web thì vào rất chậm. Trong khi trước đó chỉ có 0.1%.
Mình đã khởi động lại máy chủ , tuy nhiên sau 30 phút tải lên rất cao.
Lượng truy cập bình thường.
Mình không tìm ra được nguyên nhân. Mong các bạn giúp. Đây là các file log.
