Hi All,

Every time I run SAC, it barfs this out (all I did for this example was type
'sac' and then immediately typed 'quit'):

    Dear Katie

    Try looking at this page:

    http://www.iris.washington.edu/pipermail/sac-help/2009-August/000593.html

    It is the same issue as you are running into. This will make sure SAC
    does not perform a memory dump when you run it.
