    Yuan,
    
      The most likely cause is that the restart failed to open one of the
    files that was open() or mmap()ed at the time the checkpoint was taken.
     Based on the fact that you see this w/ a shell script, but not C code,
    my best guess is that you are encountering a problem with the file that
    the Name Service Cache Daemon (NSCD) uses.  Please see the following FAQ
    entry for more detail (including what to look for in the system logs)
      http://upc-bugs.lbl.gov/blcr/doc/html/FAQ.html#nscd
    The only known work-around is to remove NSCD from your system.
