Hi !  

I could not solve the problem yet. However, I made some cleaner debug  
messages using lib/opt instead of dbg and also had a look at the 
backtrace.  
It seems that there is no further data transfer possible after the client  
has connected to the servers. It blocks when calling mgr->redraw() and  
server->render(act) in display().

These are the backtraces (I also tried with StreamSock instead of  
Mutlicast, with similar results )

And this is the full output from OSG_LOG_LEVEL=debug ,with opt-library,  
this time with StreamSock connection, but I also get "INFO: Connection  
accepted..." with Multicast.
