SYMPTOMS
When you run an application that calls the MessageBeep function on a Windows Vista-based computer, several system page table entries (PTEs) are leaked. Under most circumstances, this minor leak is not noticeable. However, if the MessageBeep function is frequently or repeatedly called, this leak may cause the computer to stop responding (hang).
Note You can view the system PTE usage in Performance Monitor. To do this, add the Free System Page Table Entries counter to Performance Monitor.
Back to the topCAUSE
In this situation, the port class driver maps a buffer. However, this driver does not always then unmap the buffer as expected. Therefore, the system PTEs that are used to map the buffer are leaked.
