4/27    The mystery CPU usage has been found.  I stopped postfix and all my CPU
        came back.  This is on an old redhat 7.2 box.  According to top and ps
        it was only using like 4%, but really it was using 100%, why no tool to
        see what "real" usage is?
        \_ Actually, it is quite possible that postfix was only using 4% of
           the CPU.  Depending on the exact way forking is done, children of
           postfix could have been using the rest of the CPU.  If these
           children spawn and die fast enough, you will never catch them in
           top.  This has happened on Soda a few times...look at your
           process accounting logs to see what is really going on.
            \_ mucho gracias. But i don't think i have process accounting logs
