Question

我们正在使用Corda V3.2，并且使用RAFT公证人，有3个公证节点，其IP可能是：xxx.xxx.xxx.001，xxx.xxx.xxx.002，xxx.xxx.xxx.003 < / p>

不确定公证人1错误的原因是什么，公证人1的日志中反复显示以下错误：

[ERROR] 2018-08-29T06:01:49,427Z [copycat-server-/xxx.xxx.xxx.001:10001-copycat] concurrent.SingleThreadContext.lambda$logFailure$2 - An uncaught exception occurred {}

我还想了解有关“ state.ServerContext.setLeader”和“ Found Leader”在日志中的含义的更多信息，因为在公证人1的日志中，我可以在以下日志中找到似乎是公证人1试图将公证人2和公证人3都设置为负责人，不确定是否由于公证人1而导致现在不可用：

[INFO ] 2018-08-29T06:01:50,489Z [copycat-server-/xxx.xxx.xxx.001:10001-copycat] state.ServerContext.setLeader - /xxx.xxx.xxx.001:10001 - Found leader /xxx.xxx.xxx.002:10001 {}
[INFO ] 2018-08-29T06:01:52,084Z [copycat-server-/xxx.xxx.xxx.001:10001-copycat] state.ServerContext.setLeader - /xxx.xxx.xxx.001:10001 - Found leader /xxx.xxx.xxx.003:10001 {}

对于公证人2的日志，它也有两个发现的线索，一个甚至是本身

[INFO ] 2018-08-29T07:46:35,215Z [copycat-server-/xxx.xxx.xxx.002:10001-copycat] state.ServerContext.setLeader - /xxx.xxx.xxx.002:10001 - Found leader /xxx.xxx.xxx.002:10001 {}
[INFO ] 2018-08-29T07:51:07,596Z [copycat-server-/xxx.xxx.xxx.002:10001-copycat] state.ServerContext.setLeader - /xxx.xxx.xxx.002:10001 - Found leader /xxx.xxx.xxx.003:10001 {}

公证人3与公证人2的情况相同，有两个找到的线索，一个线索本身。

因此，我不确定RAFT公证人是否混乱并且无法正常工作，3个公证节点是否足以进行RAFT或至少我们需要4个公证人，这意味着什么？一个错误。 RAFT生产是否稳定，如果没有，已知问题是什么。

之前，我们为RAFT at here提出了一个问题，并被告知这是一个多个公证小组的问题，被标记为要跟踪的一个问题at here，但从最新状态来看，它是“ WONT” DO”，因此不确定这不是集群问题还是不会解决。

有人可以帮忙吗？
