【 Tikv 使用环境】生产环境（纯 Tikv 服务）
【 Tikv 版本】v7.1.5
【 Tikv-client-go 版本】v2.0.7
生产环境使用 tiup，对部分 tikv-server 进行绑核操作，并重启。
重启完毕后， PD Leader 服务的 GetRegion QPS 异常上涨 70 倍。并且 tikv-client-go 写事务失败率上涨。持续 24 小时。
当对其中一台 tikv-client-go 服务进行重启后，该 client 的 get_region qps 下降到正常水平，怀疑重启线上所有 tikv-client-go 可绕过恢复。
tikv-client-go 部分日志如下：
