刘珍 created IOTDB-2897:
-------------------------

             Summary: [wal recovery]  hang
                 Key: IOTDB-2897
                 URL: https://issues.apache.org/jira/browse/IOTDB-2897
             Project: Apache IoTDB
          Issue Type: Bug
          Components: Core/WAL
    Affects Versions: 0.14.0-SNAPSHOT
            Reporter: 刘珍
            Assignee: Haiming Zhu
         Attachments: config.properties, image-2022-04-13-11-00-43-057.png

master 600ba97481cc57dc5dedd27a3dceacd8b45419a5
问题描述：
    WAL 恢复，卡住。

复现流程：
1. 机器信息
私有云172.20.70.31   8C32G
benchmark 路径/data/iotdb/iotdb-sql/iotdb-sql/tools/benchmark
iotdb路径/data/iotdb/master_src/master_wal_v1
iotdb配置
MAX_HEAP_SIZE="24G"
MAX_DIRECT_MEMORY_SIZE="2G"
avg_series_point_number_threshold=100000000

benchmark配置见附件

2. 运行benchmark
几秒钟就可以写入完成，之后 killall -u ${current_user}
所有的memtable都不会刷盘，所以所有的tsfile大小为0.
3. iotdb启动
sync
sudo -s <<EOF
echo 3 >/proc/sys/vm/drop_caches
EOF

启动iotdb，卡住。
