是否可以改成 在readIndex的时候异步的发送心跳
不行的，如果有阻塞，会逐步 block 住所有可用线程的，没办法从根本解决问题。
这里有个判断，对于没创建连接的，会快速失败并异步建连，不应该有阻塞的。你用的什么版本？
另外，看堆栈，这是魔改过的 jraft？

我在排查为什么会timeout的时候自己加了很多日志所以行数可能对不上，版本是1.3.13.
看图片2，堆栈中checkConnection之后 park?
我打印日志的时候发现readIndex在从发送到一个掉线的节点，到发送到正常的节点相差5s，这个时候早已timeout了。然后会打印
A timeout read-index response finally returned: Status[OK]

不仅仅是日志行数对不上的问题，比如 com.galaxybase 是什么？

看不到具体代码行数，不过是 ConcurrentHashMap 里面的锁吧？这里 bolt rpc 建连也是异步的 （我的意思是想说你再抓一把线程栈可能没有这个 wait 了）
至少从现在的信息里是看不到哪里 block 的，建议用 arthas 试试能不能找到 block 在哪了
