网络波动后导致获取连接失败

```
Apache.IoTDB.SessionPoolDepletedException: SessionPool depletion detected: Reconnection failed
---> Apache.IoTDB.ReconnectionFailedException: Error occurs when reconnecting session pool. Could not connect to any server

```

```
Apache.IoTDB.SessionPoolDepletedException: SessionPool depletion detected: Connection pool is empty and wait time out(2500s)

因为使用的DDNS，中途出现IP变化网络波动后就再也连不上了，有概率出现

Start by tracing SessionPool.Reconnect and ExecuteClientOperationAsync, then inspect ConcurrentClientQueue.Take() using the reported InsertAsync path. Reproduce a DDNS address change during a connection and verify that the session pool can reconnect and recover instead of remaining empty or timing out.
