Hi Ping,<br>
<br>
For Linux it works fine, but bear in mind that top also reports all the
memory used by shared libraries (libraries used also by other
applications) as part of the memory used by that process.<br>
<br>
<br>
Cheers,<br>

Hi Ping,<br>
<br>
Which OS are you using? Because top doesn't work very well in all OSs
(for example solaris).<br>
<br>
<br>
