I use Design Management 6.0.5 on a Linux system. When I want to preview a diagram in Design Manager the preview displays the message "Unable to load diagram".

The Design Manager's Diagnostics (Application Administration -> Diagnostics -> Rhapsody Rendering Diagrams Application) shows this error message: "Model Server Failed to launch."

There are some new processes with the name mwgetmode, mwtrue and regedit. They consume 100% of my CPU. Here is the process tree (created with pstree):

inner-watchdog
    mwrpcss
    regss
        mwfwrapper
            mwadm
                mwperl
                    mwperl.bin
                        mwcore
                            mwperl
                                mwperl.bin
                                    core_services.c
                                        mwpingreg
                                            mwtrue
                                                6 x mwtrue
        6 x gegss

    ModelServer.exe
        ModelServer.exe
            mwadm
                mwperl
                    mwperl.bin
                        wstatus
                            mwstat
                                mwgetmode
                                    6 x mwgetmode
            set
    409 x java

 
I have installed already the 32bit system library libXdmcp.

Here are the entries in dm.log:
