I'm getting a few of these, don't understand why. Can anyone help?

Looks like you may be running out of physical RAM Art. 1Gig installed only right? I'd suggest reduce the number of cores running apps or add more physical RAM.

Jason you are correct that PC has 1GB. Thanks for the hint! By way of education, what in the task report or STDERR OUT led you to that conclusion?

Going from memory now, as it's a day later, I looked up the error codes on the reported task on Microsoft's website & one of them was 'out of resources'. I then looked at your host, recognised it as a quad core with nVidia GPU. Newer Cuda drivers use (a lot) more system area than the old ones for shared video memory, and Windows 7 would only have about 512meg max kernel area, which would exhaust pretty quickly under those conditions. Kernel area isn't pageable, and 512meg physical left as pageable isn't a lot that can stay resident for 4xCPU apps + optionally a GPU app either (Plus everything else that might be running).
[Edit:] here's the example of system resources reserved for my 480 (from nVidia control panel system information):
[Display]
Operating System: Windows 7 Professional, 64-bit (Service Pack 1)
DirectX version: 11.0
GPU processor: GeForce GTX 480
Driver version: 266.58
DirectX support: 11
CUDA Cores: 480
Core clock: 820 MHz
Shader clock: 1640 MHz
Memory clock: 2088 MHz (4176 MHz data rate)
Memory interface: 384-bit
Total available graphics memory: 3322 MB
Dedicated video memory: 1536 MB GDDR5
System video memory: 0 MB
Shared system memory: 1786 MB
Video BIOS version: 70.00.1A.00.80
IRQ: 16
Bus: PCI Express x16
That's what I would call a 'Decent chunk' out of my 4Gig installed physical RAM. What that is used for is pretty involved, but one of the fundamental WDDM driver model extensions that allows the driver to recover without rebooting, as opposed to hard lock or old-school BSOD

OK Thanks. I had a couple GB of the right stuff in my junk box now running in that PC. Available RAM shown by Task Mgr jumped from ~250MB w/4 tasks running to 1,300MB. Will be watching for any more errors. There isn't much else running except W7 64 bit hotel loads and an AV program. The offending PC is devoted to BOINC.
Regards and thanks again
