Is the memory not reclaimed for Delphi apps running on Windows Server 2008 (sp1)?

Question

We have a D2007 application whose memory footprint grows steadily when running on Windows Server 2008 (x64, sp1).
It behaves normally on Windows Server 2003 (x32 or x64)

Answer 1

There is a new sysinternals tool called VMMap which visualizes the allocated memory. Maybe it could show you what the big memory blocks are.
