Platform: Win2K, LabView 6.02i, NI-DAQ 6.9.2, PCI 6071E sampling board.
I have an application with a loop containing an AI Buffer Read VI. When I run the application, the Task manager shows that the CPU load steadily increases (like there is a "CPU leak" 🙂 ) until it reaches 100% and then no other module (like application GUI) can work. The profiling shows that the only "heavy" VI is the AI Buffer Read.
One more strange thing: if I open another window (like Windows Explorer) or move some windows on the screen, while running AI Buffer Read, the CPU load jumps by 20-30% and does not decreases afterwards.
Any help will be appreciated.
