Spring Boot WebSocket Rabbitmq Stomp Broker Not Keeping Connection - spring-boot

Question

Couldn't find any other questions related to this specific error.
I can't seem to hook up my Spring Boot WebSocket demo project with RabbitMQ. Note that everything works fine when using the "simple" broker, but when hooking up the stomp broker with Rabbit, I get the following error (keeps trying to reconnect):
Java HotSpot(TM) Client VM warning: You have loaded library /tmp/libnetty-transport-native-epoll8916930274033685449.so which might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.

Just to be sure I'm pointing at the right point, I run:
matthew#matthew ~/code/chat $ epmd -names
epmd: up and running on port 4369 with data:
name rabbit at port 25672
Here's my WebSocketConfig:
package com.chat.shared.websocket;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.env.Environment;

import org.springframework.messaging.simp.config.MessageBrokerRegistry;

import org.springframework.web.socket.config.annotation.StompEndpointRegistry;
import com.chat.user.services.UserPresenceService;
#Configuration

public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {

}

}

registration.taskExecutor().corePoolSize(8);
registration.setInterceptors(presenceChannelInterceptor());
}
}

I have a feeling my problem has to do with the netty/reactor dependencies I'm bringing in. Any input is appreciated.

Answer 1

First of all you really should be consistent with the Spring Framework (Boot) dependencies and don't use Reactor 1.0.0, but exactly the latest 2.0.7.RELEASE.
Not sure from here that you need reactor-tcp at all...
Regarding RabbitMQ part. You should be sure that you really have installed the STOMP plugin: https://www.rabbitmq.com/stomp.html.
Note: the default STOMP port is 61613.
