为提高效率，请提供以下信息，问题描述清晰能够更快得到解决：
【TiDB 版本】
v4.0.11
【问题描述】
insert into lhl1 select * from lhl; 批量插入数据 连接中断
报错：[Err] 2003 - Can’t connect to MySQL server on ‘192.168.150.202’ (10038)
lhl表中有2000万条记录
若提问为性能优化、故障排查类问题，请下载脚本运行。终端输出的打印结果，请务必全选并复制粘贴上传。
出现这个报错建议先自行检查下集群环境中 TiDB Server 的 log ，看下 TiDB Server 是否因为异常重启过 ~

请自行检查下 insert select into 语句执行期间，TiDB Server log 是否有出现过重启（上面的日志应该非语句执行期间的日志），比如是否有出现过 Welcome to TiDB 关键字 。
或在语句执行期间，TiDB Server 的 log 是否有报错信息～
已经查到原因了是OOM了
如果是因为这个 SQL 导致的 TiDB OOM ，可以将每次批量插入的数据限制的更小点。
