Error flushing statements

[Evre-wuwy]

Describe the bug

Every time I update the table, I do a full update (delete first and then insert) However, when executing insert statements recently, Error flushing statements often appear.

Code example

Good day, @Evre-wuwy! What clickhouse-java client version do you use? Have you tried with latest? Would you please add more information:

Thanks in advance!
