Bắt đầu bằng cách kiểm tra com.alipay.oceanbase.rpc.table.ObTable.ObTableConnectionPool, đặc biệt là cleanerExecutor, và tái hiện một lần ghi bằng Direct-Load API trên nhiều node trong khi thu thập log jstack. Hoàn tất khi các luồng không phải daemon có thể kết thúc bình thường và JVM thoát sau khi thao tác Direct-Load hoàn thành.
