<DIV>Dear Luke,</DIV>
<DIV> </DIV>
<DIV>Thanks for your reply. It is a 32-bit processes. </DIV>
<DIV> </DIV>
<DIV>Sorry to tell you my analysis early. Last Saturday I found our Corba
server application has a large sum of unusable memory through vmmap
tool, it amounts to 1.2G. After investigation, I found it is due to auti-virus
software I installed, the software seems monitor and tag the memory
allocation of every user mode process.</DIV>
<DIV> </DIV>
<DIV>Anyway, thanks you very much.</DIV>
<DIV> </DIV>
<DIV>Regards</DIV>
