Try creating another session on MOZART when sd is running on BLUES. It will immediately shown on sd on BLUES. Or, if you just wait 5 minutes or more, the "missing" session will be shown on BLUES. It is a normal behaviour of sd. If an sd creates a new session, it sends packets to notify a session is alive. The packet is sent either (1) immediately after the session is created, or (2) every 5 minutes. So, when you start sd, you have to wait max. 5 minutes before the sd shows all pre-existing sessions. It may be hard to recognize this behaviour, since sd plays a trick with the file ~/.sd_cache to reduce the delay. Please verify the above scenario. I believe presence of mrouted is irrelevant.
