一、该问题的重现步骤是什么？

我们买的商业版，还请大神看到能回复我一下。谢谢！

1. 部署了服务提供商，消费者，都注册到了nacos，使用postmain进行测试服务消费端ctroller提供的请求，低频率的请求没问题，快速点击发送请求会出现如下异常信息，此时nacos中服务提供商显示：健康实例数:0,阀值保护:true　等过一会刷新服务列表就好了，再次请求正常。

2. nacos服务列表中对某个服务下线后，刷新列表该服务状态又是上线了，编辑后的信息不会保存吗？

二、你期待的结果是什么？实际看到的又是什么？

三、你正在使用的是什么产品，什么版本？在什么操作系统上？

四、请提供详细的错误堆栈信息，这很重要。
