CorDapp崩溃，SSL握手超时异常，后跟java堆空间错误

时间：2018-02-12 06:58:54

标签： blockchain corda

我们已经创建了一个示例CorDapp，并将其部署在AWS上的分布式网络中。我们的目的是验证应用程序是否可以存储100万笔交易。但是，当针对不同输入多次执行单个流时，应用程序崩溃时会出现SSL握手超时异常，然后是java堆空间错误。

这次崩溃/异常可能是什么原因？

关于CorDapp：

应用程序定义了一个在各方之间创建发票的流程。 create事务由A和B节点签名。   创建事务请求始终发送给A方。它在验证后签署事务。   然后，甲方将请求转发给B部分进行签名。一旦双方都签署了该事务，就会将其发送到最终提交流程。   Party C只是提交交易。没有党C签字   状态和分类帐存储在所有三个节点上。

申请已

  • 3个聚会节点（A，B，C）
  • 2个公证节点（1个简单，1个验证）
  • 1个oracle服务节点
  • 1个控制器节点

条件：

我们开始使用JMeter执行创建流程（25个线程在循环中运行，每秒最多一个请求）。最初，应用程序响应良好，响应时间约为每秒2~4个事务。   然而，随着承诺交易数量的增加，业绩开始变得无能为力。   在大约200K的事务中，应用程序因Java堆空间错误而崩溃。   我们已将java Corda进程的最大堆大小设置为4GB。

我们的观察结果：

  1. 始终是B节点崩溃。在我们的Corda流程中，此节点的职责是签署事务，然后将其提交到FinalityFlow中的数据库。
  2. 在B节点上使用netstat命令，它在CLOSE_WAIT1状态下显示多个连接，在FIN_WAIT1状态下显示很少。
  3. 从日志看来，最初有SSLException声明SSL握手超时执行流程。在多个此类异常之后，存在Java堆空间错误。
  4. B节点在特定时间/条件之后停止与其他节点通信，这反过来导致所有这些异常。然而，我们不知道发生这种情况的原因。

1 个答案:

答案 0 :(得分：0)

尝试增加JMeter的Java堆大小。默认情况下，JMeter使用1 GB的堆运行，这可能不足以进行测试，并取决于要运行的线程数
