> URL: https://jira.jboss.org/jira/browse/JBREM-1099
> Project: JBoss Remoting
> Issue Type: Bug
> Security Level: Public(Everyone can see)
> Affects Versions: 2.5.0.SP2 (Flounder) , 2.2.2.SP11

> The multicast detector does not work properly in environments where plenty Remoting invokers are
> used, such as the case of EAP 4.3 where you have invokers for EJB3, EJB2, JMS...etc.
> What happens is that org.jboss.remoting.detection.AbstractDetector.createDetection(), it creates a
> detection message based on the server invokers registered locally. As there's one more invoker in
> EAP 4.3.x, the message size exceeds the 4000 limit.
> This leads to errors like:
> 2009-02-12 15:19:26,846 DEBUG [org.jboss.remoting.detection.multicast.MulticastDetector] heartbeat failed
> java.io.IOException: Message too long
> at java.net.PlainDatagramSocketImpl.send(Native Method)
> at java.net.DatagramSocket.send(DatagramSocket.java:612)
> at org.jboss.remoting.detection.multicast.MulticastDetector.heartbeat(MulticastDetector.java:226)
> at org.jboss.remoting.detection.AbstractDetector$Heartbeat.run(AbstractDetector.java:716)
> at java.util.TimerThread.mainLoop(Timer.java:512)
> at java.util.TimerThread.run(Timer.java:462)
> The size of the buffer where the Detection message is sent comes from:
> private final class Listener extends Thread
> {
> boolean running = true;
> public Listener(String name)
> {
> super(name);
> }
> public void run()
> {
> byte[] buf = new byte[4000];
> DatagramPacket p = new DatagramPacket(buf, 0, buf.length);
> //p.setAddress(addr);
> //p.setPort(port);
> while(running)
> {
> listen(p, buf);
> }
> }
> }
> The size of the buffer needs to be made configurable.
