    TAO VERSION: 1.5.3
    ACE VERSION: 5.5.3

    HOST MACHINE and OPERATING SYSTEM: Fedora Core III:

    DOES THE PROBLEM AFFECT:
        EXECUTION: YES
Affected TAO, Collocated objects???

    SYNOPSIS:
Accessing collocated object after having shutdown the server ORB will block forever.

    DESCRIPTION:
I have two ORB instances in my process - the ClientORB and the ServerORB.
I have a oneway remote method (ShutdownInterface->shutdown())calling ServerOrb->shutdown( false );
The main thread accesses then a collocated object (exampleObject_var->funct()) through ClientORB and gets stucked/blocked when exampleObject_var was gained (ClientOrb->string_to_object()) with corbaloc:iiop:127.0.0.1:9000/ExampleObject or corbaloc:iiop:localhost:9000/ExampleObject.
No problems when I use another IP or domain available on that machine. This makes me to tip on a problem with collocated objects.

    REPEAT BY:
ServerORB->shutdown( false );
Object_var o = ClientORB->string_to_object( "corbaloc:iiop:127.0.0.1:some_IP/some_service_ID" );

SpecialService_var ssv = SpecialService::_narrow( o.in() );

    SAMPLE FIX/WORKAROUND:
Do not use localhost or 127.0.0.1
