[xfworld (魔幻之翼)]

先上集群配置信息，描述相关节点的状态
然后 write tcp 10.18.13.226:4000->10.18.13.224:28952: write: connection reset by peer 这两个节点是什么关系？ 请描述清楚

[问题澄清]

[error] write tcp 10.138.1.98:4000->10.130.64.10:36760: write: connection reset by peer

[原因分析]

说明前台自己断开了连接，TiDB发送的消息没有被接收，TiDB 暂时无超时机制。

[解决方案]

如果 TiDB 日志中很频繁的出现这个信息，可能因为前端有负载均衡在探测后端服务是否存活，属于正常信息，可以改成使用 status 的端口（默认是 10080）
