mmm it seems we are not using buggy driver because our node are ubiquity picostation with madwifi, moreover we have the same message from eth0 ( wired interface ) ... and not seems we have loop in every node... and now mdns is disabled and we continue to have the same message... here is the realtime topology: http://131.114.250.100/status.php http://131.114.250.100:2006/
