Question

当我使用节点驱动程序运行Corda 3节点时，我间歇性地得到以下异常：

[INFO ] 15:09:20,485 [driver-pool-thread-0] (DriverDSLImpl.kt:169) internal.DriverDSLImpl.invoke - Exception while connecting to RPC, retrying to connect at localhost:10013 {}

我该怎么做才能解决这个问题？每次启动节点时都不会发生这种情况。

Answer 1

目前，节点驱动程序有时不会干净地关闭节点进程。在再次运行节点驱动程序之前，您需要终止任何延迟的Java进程。

在osX上，您可以通过运行：

来完成此操作

killall java -9

在Windows上，您可以通过运行：

来执行此操作

wmic process where "name like '%java%'" delete

使用Corda 3节点驱动程序时连接到RPC时出现异常
