Two applications share memory by MMF.
A create MMF (about 1GB), B open that MMF file by name.
When I see Windows Task Manager, A has 1GB memory.
But, after several closing and launching B app again,
(or after 1 days later? I’m not sure how to reproduce)
A’s memory in Windows Task Manager is below 1K bytes.
My guess is,
maybe because A app doesn’t do anything after create MMF,
so, Windows thinks MMF is belong to B app. (Just guess).
My OS is Windows 2003 Enterprise x64, SP2.
Is there somebody who knows the reason?
Thanks in advance.
It’s because of memory working set minimize.
Thanks for everyone. 🙂
