Indeed the membership messages are missing. It takes several minutes until 
membership message arrives. However, once the message arrives, Spread 
starts to work normally.

I think it would not make sense to keep message queue after TCP 
disconnect, specially if the client cannot reconnect anyway (name not 

Looks like the Spread daemon is somewhere blocked at start, however, it 
still does accept and handle TCP connections.

As I said, the problem does *not* occur on Linux. On Solaris 10, it seems 
that Spread works better when compiled with SunStudio rather than gcc (I 
never got membership message when compiled with gcc, but maybe I did not 
wait long enough).

Any help would be very much appreciated.
