When I run Corda 3 nodes using the node driver, I intermittently get the following exception:
[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 {}

What can I do to fix this? It doesn't happen every time I start the nodes.
回答1:
Currently, the node driver sometimes does not shut down the node processes cleanly. You need to kill any lingering Java processes before running the node driver again.
On osX, you can do this by running:
killall java -9
On Windows, you can do this by running:
wmic process where "name like '%java%'" delete
