I've created a JIRA issue to look into this problem: http://jira.jboss.com/jira/browse/JBREM-991 "Investigate MulticastDetector message flood". As I noted, there is some odd looking behavior in MulticastDetector.listen(): | else | { | // for now, assume anything *not* of type Detection | // is a prompt to send out detection msg | heartbeat(); | } | As long as you're playing with the MulticastDetector, you might want to comment out this clause and see what happens.
