dubbo 报错问题记录:may be version or group mismatch

  凌晨时候钉钉告警群里一直大量报错：

   在某一个时刻，大量的dubbo 异常。 早上起来先去elk里面查询是不是并发量的问题，查了下这个时刻 并发量每秒大概300-400的量，和平时差别不大。然后找到具体的接口，通过elk的 request_time 发现有个别接口响应时间达到 1秒多,而调用的dubbo服务

@Reference(timeout = 1000)

private DriverInfoService driverInfoService;

时间超过了1秒。但是为什么会报错那。。。 正常来说又不会出现问题

看了 消费者，报的的dubbo 异常，之后再查看生产者，查了下这个时间段日志是正常的。 但是最后查看dubbo的启动日志时候：

[2019-07-18 03:07:28] Dubbo service server started!

dubbo服务 在这个时间段内竟然重启了。。。

之后联系运维，原来是他们在凌晨这个时间点 重启了swap top5的服务。刚好这个时间段请求量比较大，zk注册的时候还没有注册上。导致请求了重启的那个机器ip上面。从而出现了大批量的报错信息。
