k8s环境启动3节点集群，经常有一个节点长时间卡在Nacos is staring…状态，pod启动两三分钟后alipay-jraft.log日志文件依然为空，无选主日志，pod多次重启后有概率可以成功启动。
其他正常节点，一般启动后5s左右alipay-jraft.log日志文件就会有日志输出。
2.4.0.1等之前版本无该问题，希望尽快修复，谢谢。

无法复现此问题，能否在复现时 使用jstack指令输出一下堆栈， 看下main方法的堆栈位置是卡在哪里。

我这边是大概率(复现率90%以上)复现的，我下面贴下jstack信息，有个死锁

拍照看起来太麻烦了，同时也无法检索， 能否上传一份stack文件。
