Camel Spring remoting with Artemis Proton/Qpid client - hangs sending message - spring

Question

When i use the Camel spring remoting configuration to send some message, both the producer and consumer are running in different JVM.
using Apache artemis 2.14.0 version
version of camel (2.20.0), qpid (0.54.0), pooled-jms (1.1.1)
i was using the LoadMessageSupport class to push message, i see the camel routes are invoked and below debug log message.
I noticed a producer session enabled in the Artemis console.
Any clue, how to debug this or what might cause this issue.
There were some netty related debug errors which i safely ignored.

java class running the context, used to invoke the remote spring bean method.
Using below java class to push message to Artemis queue
package com.myexample;
public class LoadMessageSupport {
public static void main(String ...strings) {
ApplicationContext appContext =null;
try {
appContext = new ClassPathXmlApplicationContext("file:/paht/to/context/message-handler-context.xml");

message = "{ \"itemDesc\" : \"test description\" }" ;

Answer 1

When i was trying earlier, seems like my VM didn't have sufficient memory.
free -h indicate only 500MB left out.
After restarting the VM the message is now sent to Artemis borker.
