Hi
With 5.2.0, I have some explicit log traces which can help to find the origin of the problem. I just opened the AMQ-2774 case. The problem appears when - the multicast discovery process discovered a distant broker. a line "Establishing ..." appears in the log file - But the connection is not established (for any reason) no line "has been established" appears in the log file - the connection is broken a line "bridge to Unknown" stopped appears in the log file Then, even if the distant broker is restarted, the current broker doesn't try to establish a connection with it (no new "Establishing ..." line appears) It seems to be the same in fuse 5.3.0.6 version.
