Cần người sửa server XAMPP sau khi Crash thì Mysql ngốn CPU tới tận 50 80%. Trong khi bình thường sài chỉ có 2 3% thôi

Ngày hôm nay cái xampp trên Window của mình cứ bị cái lỗi này hoài, 2 tiếng bị một lần. "[login to view URL] warning : Table is marked as crashed and last repair failed warning : Size of indexfile is: 54710 Expected: 24576 error : Wrong base information on indexpage at page: 2 error : Corrupt" Mấy lần trước mình chọn export db ra, rồi xóa xampp cài lại, thì CPU bình thường sài có 1 2% à. Nhưng giờ lỗi thường xuyên bị, chán cài lại quá, giờ có bạn nào giúp mình tìm hiểu nguyên nhân và khắc phục làm sao mà ko phải cài lại database không? hoặc nếu có cài lại thì cài lại một cách nhanh nhất bằng lệnh ấy.
