[Opensg-users] Problem Terminating ClusterWindow with MulticastConnection

[Christoph Fuenfzig]

Hi, we have problems when terminating a ClusterWindow with ConnectionType "Multicast" (Windows 2000, ICL 7.1). The application always throws an exception "sendto: WSAEADDR-NOTAVAIL" on termination of the ClusterWindow. The problem is in MulticastConnection::stopAliveThread: void MulticastConnection::stopAliveThread() {     char tag;     if(_aliveThread)     {         _stopAliveThread=true;         DgramSocket s;         s.open();         s.sendTo(&tag,                  sizeof(tag),                  SocketAddress(_aliveSocket.getAddress()));         BaseThread::join( _aliveThread ); //!!        ThreadManager::the()->removeThread(_aliveThread);         _aliveThread=0;         if(_aliveSocket.waitReadable(0))             _aliveSocket.recv(&tag,sizeof(tag));         s.close();     } } The address SocketAddress(_aliveSocket.getAddress()) seems to be invalid :-( Is this a known problem? Thanks, Christoph
