3副本3C3D，各节点状态正常，Benchmark在执行读写，datanode 间隔2分钟，持续刷如下log：
 !image-2023-02-03-10-35-48-860.png! 

测试环境
1. 192.168.10.62/66/68/64   72CPU 256GB
ConfigNode 和DataNode在192.168.10.62/66/68
    路径是/data/liuzhen_test/r_0129_573097a
Benchmark在192.168.10.64，/data/liuzhen_test/3c3d_longtest/bm_v1
2. 配置参数
ConfigNode参数：
MAX_HEAP_SIZE="8G"
cn_target_config_node_list=192.168.10.62:10710
DataNode参数：
MAX_HEAP_SIZE="192G"
MAX_DIRECT_MEMORY_SIZE="32G"
dn_max_connection_for_internal_service=300
dn_target_config_node_list=192.168.10.62:10710,192.168.10.66:10710,192.168.10.68:10710

Common参数：
schema_replication_factor=3
data_replication_factor=3
iot_consensus_throttle_threshold_in_byte=536870912000
disk_space_warning_threshold=0.01

3. 启动Benchmark 7*24小时读写
配置文件见附件。

4.查看datanode日志
3个节点都有问题描述中的现象。
