Have you ever had problem transfering multiple files in Vista, many people complain that errors keep showing up during the transfer process or that no error shows up and the transfered files just aren't there. This is due to a Vista error commonly know as a Vista "Out of Memory" error.
Windows Vista "out of memory" errors are intimately connected with the way the operating system manages virtual address space. The "out of memory" errors in Windows Vista are generated by applications that have eaten up all the virtual address space allocated to them.
"Every memory allocation, file mapping, or library that is loaded by an application consumes space in this virtual address space. When the application consumes all its virtual address space, any additional such operations fail. Although all applications should be coded to handle memory allocation failures, many applications do not recover correctly from such failures. Therefore, the programs may become unstable or stop responding after they recover from such failures", Microsoft informed.
"To address this problem, Microsoft is changing the way that the video memory manager maintains the content of video memory resources. This change is being made so that a permanent virtual address range does not have to be used for each virtualized allocation. With the new approach, only allocations that are created as "lockable" consume space in the virtual address space of the application. Allocations that are not created as "lockable" do not consume space. This approach significantly reduces the virtual address space that is used. Therefore, the application can run on large video memory configurations without reaching the limits," Microsoft added.
