This is coming from DAQ or another driver, and it indicates that
the OS isn't able to allocate a physical, locked page of memory
for the driver to use. It needs the page to be physical and
locked into memory so that it can't be paged out and therefore
is available at interrupt time and can be used with DMA transfers.

I suspect that the error doesn't occur with one page, but instead
indicates that a buffer is too large or that too many tasks are
in progress at once for the amount of RAM in the computer.
You may be able to remove other drivers or OS extensions to
get by, but the real solution is probably to add RAM. If there
is plenty of RAM, this may i
ndicate a problem with the driver;
so you may want to contact NI support.
