Error description

  • In an Operations Center hub/spoke configuration, the hub server
    can crash
    during hub/spoke communication exchanges.
    
    
    On AIX, dbx will show:
    
    Segmentation fault in pkFreeTracked at 0x100004444 ($t384537)

Local fix

  • Disable the use of the server's command help.
    To do this rename the Hub server's command help file to
    something else.  This can be done whilst the server is still
    running.
    
    For example;
    Running server with LANGUAGE fr_FR.
    Find the help file in the 'fr_FR' subdirectory of where the
    server executable is installed.  For example:
    /opt/tivoli/tsm/server/bin/fr_FR/dsmfr_FR.hlp
    
    Rename that file to something else like
    /opt/tivoli/tsm/server/bin/fr_FR/dsmfr_FR.hlp.save
    
    After rename of the server's help file, one won't be able to
    get help content using the HELP command.
    Later when the fix is available, rename the help file
    back to it's original name.
