After calling OpcUaServer.shutdown(), I have leaking threads named: milo-netty-event-loop-x

[fatih-algan]

Hi,

After I terminate the OpcUaServer via calling shutdown(), I see that the shared event loop threads created by the NioEventLoopGroup are not terminated. The event loop group is created by the sharedEventLoop() method of the org.eclipse.milo.opcua.stack.core.Stack class.

Is this a bug or what do I need to do to have those threads get cleaned up/terminated properly?

Thanks in advance.

When your application is done with Milo entirely you can call one of the Stack.releaseSharedResources functions.
