That could have been an implementation bug (seen similar with agents), 
or a reporting bug, or just getting the wrong value. On some systems, 
there may be multiple values, expressed as kbytes, mbytes, etc. in order 
to fit within bit constraints, or on others they split values into low 
and high words to achieve the same thing.
