ds调度clickhouse SQL，经常会报错：Socket closed

[finn199209]

所用的dolphinscheduler版本为3.1.7，jdk版本是jdk13，clickhouse服务一切正常，调度clickhouse SQL出现如下报错：ERROR] 2024-03-12 15:20:16.877 +0000 - sql task error
java.sql.BatchUpdateException: Socket closed, server ClickHouseNode [uri=http://00.000.0.00:0000/iot_es, options={max_partitions_per_insert_block=500,insert_deduplicate=0,socket_timeout=400000000,max_memory_usage=60000000000,max_execution_time=3600,max_bytes_before_external_group_by=20000000000,max_bytes_before_external_sort=10000000000}]@196492319
是偶尔报表，出现概率20%左右，请问是什么原因？
