    ****************************************************************
    When stopping ClearCase on an HP-UX system which had been
    running a substantial load on a multiprocessor system, it
    was possible to receive errors unmounting some VOBs, which
    in turn prevented successful unmount of the system viewroot.
    

Problem conclusion

  • This problem is fixed in ClearCase 8.0.0.9 and 8.0.1.2.
