Use Spring Boot, Mybatis, TDEngine Java Driver connect to TDEngine on the same machine，after running some time(about one or two day), JVM crash and left a crash report file

TDEngine server version: 2.6.0.28
JAVA JDBC driver version: 2.0.40
JAVA jdk version: 1.8.0_351

Use Case:
write data per second ，the sql like this:
INSERT INTO eblock${info.type}pack_t_v${info.type} USING eblock${info.type}_pack_t_v
TAGS (#{info.type})
values (#{info.recordTime},#{info.receiveTime},#{info.packUUID}...

and search data per 30 second, the sql like this:
select * from emonitor.eblock${bmuType}_pack_t_v


record_time > #{lastSyncTime}


order by record_time ASC limit #{pageSize}

JVM crash report:

A fatal error has been detected by the Java Runtime Environment:

2.x 版本目前官方已经不维护支持了，请迁移升级到最新的 3.x 版本吧。操作手册为：https://www.taosdata.com/tdengine-engineering/17753.html。3.x 和 2.x 相比是全方位更加优越的，关于3.x 的主要特性可以结合这篇文章和官方文档一起了解：https://www.taosdata.com/tdengine-engineering/21550.html

开源版3.x 支持操作系统参考：https://docs.taosdata.com/reference/support-platform/
