page fault in nipalk.sys when writing large file , system crashes

[jcnoble]

When reading from VXI 2211 and writing to a file the system crashes with a page fault error in nipalk.sys. I tried loading new drivers for VISA, VXI, even DAQ which I don't use. Where does nipalk.sys come from??

This is the low level device driver used by all NI hardware device
drivers. PAL stands most probably for Platform Abstraction Layer and
what that means it is providing an uniform device driver API for
managing memory, IO addresses, DMA channels and Interrupts. Most
probably this NIPAL device driver API is almost the same on all
platforms NI develops modern hardware drivers for. This allows easier
porting of device drivers to new hardware as the big work for porting a
hardware driver is about porting this NIPAL device driver.

I
would not think that disk writing is the real culprit here, but it may
trigger a problem occuring earlier during VXI access.

Hello jcnoble,
If you experience a crash in any National Instruments software component (if you look at the Properties for nipalk.sys, you should find a Company tag that says "National Instruments Corporation" or similar), I would first recommend upgrading all software to the latest available version -- see http://www.ni.com/downloads/ >> Drivers and Updates >> Current Software Versions. You may also want to search the NI KnowledgeBase at http://www.ni.com/support/ for patches and Service Packs that may apply. If after upgrading, you continue to experience failures, I would strongly recommend that you contact National Instruments Support via phone or email at http://www.ni.com/support/. To expedite your support, please have all of the details regarding your i
ssue handy. This includes the crash information (bugcheck, fault, stop code and parameters), context information on how to reproduce the crash, memory dumps, installed hardware (computer brand/model, NI devices, third-party devices), and installed software (OS version, OS Service Pack, NI software, and third-party software including the versions). I am confident that our Applications Engineers can resolve your issue in a timely fashion and make your application a success.

Sincerely,
Jeremiah -- Staff Product Support Engineer -- Systems Software
