That's just Visual Studio logging that an exception was thrown. It's
normal, and handled internally to omniORB.

In what circumstances?

CORBA::COMM_FAILURE means that omniORB was using a connection and it
broke; CORBA::TRANSIENT can be caused by various things, but most often
it has a minor code of TRANSIENT_ConnectFailed, which means that omniORB
tried to connect to the server's port, and the connection was refused.
