- 【TiDB 版本】：v4.0.8
- 【问题描述】：golang 程序压测tidb 出现异常
在docker 中使用golang 100并发 压测tidb ，批量写入数据
偶尔出现以下报错：
{“level”:“ERROR”,“time”:“2021-01-20 17:54:19”,“file”:“service/devicerecord.go:76”,“msg”:“BatchInsert Failed:device record batch insert error: db insert error: driver: bad connection”,“logId”:“3789006240”,“requestId”:“3789013727”,“module”:“gocrius”,“localIp”:“192.168.240.239”,“uri”:""}
在tidb 日志中会有如下warn 出现：

请问上述的warn 是否会导致程序端的 连接失败的报错 ？
