supercocoa opened a new issue #9278:
URL: https://github.com/apache/dubbo/issues/9278


   
   
   ### Environment
   
   * Dubbo version: 2.7.x  3.x
   * Operating System version: any
   * Java version: any
   
   ### Steps to reproduce this issue
   
   1. 关掉zk
   2. providder断点停住，模拟服务hang住或宕机的死连接情况
   3. consummer到时触发ReconnectTimerTask
   4. ReconnectTimerTask里判断连接可用，然后走到else触发超时重连逻辑
   5. 
超时重连的reconnect的实现里面又去判断跟step4一样的连接可用逻辑，导致没有去强制重连，等于这个reconnect里的逻辑实际无法生效，即没有在需要重连的时候去强制重连，最终导致死连接的服务没有被摘流，consermer一直往死连接的服务发请求

   ### Expected Behavior
   
   死连接情况，心跳超时重连的时候需要强制重连
   
   ### Actual Behavior
   
   死连接情况，心跳超时重连的时候实际没有去重连
