Corda 公证处正在进行处理

目前，我正在使用Corda V3.1，有一个问题我无法找出其根本原因。应用程序处理事务时会发生错误行为。它在以下日志的最后一步被挂起：

>> Verifying contractCode constraints.
>> Signing transaction with our private key.
>> Collecting signatures from counterparties.
>> Done
>> Obtaining notary signature and recording transaction.
>> Requesting signature by notary service
>> Requesting signature by Notary service(hanged here)

我没有做任何改变，但它停止了工作。从日志中，我可以看到：

最后两个步骤一次又一次地重复。解决此问题的唯一方法是清理和重新部署节点，但这肯定是不正确的。有人能帮忙吗？非常感谢。

因此，根据您的描述，不清楚您是如何运行corda节点的

问题是corda节点之间的通信有问题，但原因尚不清楚。如果它是在本地主机上运行的，那么这真的很奇怪

如果你在云中运行这些，我会尝试重新生成你的节点配置，或者再看看corda节点的网络地图，因为它肯定会变得不稳定

也可能是它试图运行的cordapp在尝试在节点或公证人上执行时出错

为了确定corda更新是否解决了这个问题，您可以更轻松地将其与一些较新的开发人员示例一起使用

最基本的始终有效的示例是yo cordapp（）。尝试运行它，看看是否可以将问题隔离到流或corda

这是哪一版本的Corda？嗨，Joel，这是V3.1，你在运行什么Corda应用程序？你在做什么来触发这个错误？
