Error description

  • Under a very-rare and currently unknown set of circumstances, an
    IBM Rational ClearCase host running the AIX operating system may
    experience a system crash in 'mvfs_aix_lookup_component'
    
    The AIX crash stack trace in this case read:
    ...
    mvfs.o:mvfs_aix_lookup_component+0002C8
    mvfs.o:mvfs_lookup_ctx+000510
    mvfs.o:mfs_lookup+000050
    mvfs.o:mfs_aix_lookup+000080
    ...
    
    The issue is currently believed to be a one-time occurrence but
    is believed to be a rare race condition.
