Windows task manager: Virtual Memory size exceeds Memory Usage
Posted by 50295@web.de on February 22nd, 2006


Hi -

I've been taking a closer look at the task manager a lot these days and
I notice that in some processes, the memory usage stats exceed the
virtual memory size. How is that possible???

I'm assuming virtual memory here does not mean swap/paging file.

Thoughts? Anyone?

Thanks,

commit
Memory allocated to programs and the system. Because of virtual memory, the
value listed under Commit Peak memory may exceed the maximum physical
memory.]]
From Task Manger HELP

[[Commit Charge (K)
Memory allocated to programs and the operating system. Because of memory
copied to the paging file, called virtual memory, the value listed under
Peak may exceed the maximum physical memory. The value for Total is the same
as that depicted in the Page File Usage History graph.]]

Thanks for your help, but no it does not help. I understand the Virtual
Memory Mechanism, and I know that it is not the same as the paging/swap
file of physical memory. I am still baffled that the report virtual
memory statistics exceeds the reported memory usage.
