    ACE version: 6.3.3
    TAO version: 2.3.3

    OPERATING SYSTEM:
    Windows 10

    COMPILER NAME AND VERSION:
    Embarcadero Seattle C++ builder update 1. bcc32.exe version 7.11

    DOES THE PROBLEM AFFECT:
    COMPILATION?
    NO
    LINKING?
    NO
    EXECUTION?
    YES

    SYNOPSIS:
    IOR contains several endpoints(3 - 4), valid endpoint is last one. ORBUseParallelConnection is 1 and ORBUseSharedProfile 1.
    Connect to several endpoints is consecutive.

    DESCRIPTION:
    Server is available through Naming service (Windows service). Client connect to server through Naming service. Client parameters is following: -ORBDebug -ORBDebugLevel 10 -ORBDottedDecimalAddresses 1 -ORBInitRef NameService=corbaloc:iiop:UAPC1410:2001/
    NameService -ORBListenEndpoints iiop://:10010/portspan=10&reuse_addr=0&hostname_in_ior=localhost -ORBLogFile corba.log -ORBObjRefStyle URL -ORBParallelConnectDelay 100 -ORBSvcConf svc.conf -ORBUseParallelConnects 1 -ORBUseSharedProfile 1 -RequestTimeout 0

    svc.conf:
    static Advanced_Resource_Factory "-ORBAMIResponseHandlerAllocator thread -ORBReactorType select_mt"
    static Client_Strategy_Factory "-ORBTransportMuxStrategy MUXED -ORBClientConnectionHandler MT"
    static Server_Strategy_Factory "-ORBTransportMuxStrategy MUXED -ORBConcurrency thread-per-connection"

    Server provide IOR with several endpoints. (IOR: corbaloc:iiop:1.2@PS-IIOKA:10000,iiop:1.2@172.21.4.27:10000/StandardImplName/HomePoa/UserSecurityHome).

    On log file I found suspicious output (which should block.) below is part of log:

    My question is: why parallel connect does not work? Do you have any glue?

    Thanks in advance.
