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.

milo/opc-ua-stack/stack-core/src/main/java/org/eclipse/milo/opcua/stack/core/Stack.java

Lines 192 to 197 in f1ce134

	/**
	* Release shared resources, waiting at most 5 seconds for the {@link NioEventLoopGroup} to shutdown gracefully.
	*/
	public static synchronized void releaseSharedResources() {
	releaseSharedResources(5, TimeUnit.SECONDS);
	}
