I’ve gotten a few KERNEL_DATA_INPAGE_ERROR (0x0000007A) bluescreens with a
status code of STATUS_INSUFFICIENT_RESOURCES (0xC000009A), which apparently
“is caused by a lack of nonpaged pool resources”.
To understand what is really going on, I like to try to recreate the same
bluescreen with intentionally bad code, however, I’ve been unable to in this
case.
I’ve written a program that just sits around trying to allocate nonpaged
pool memory, and thus, sucks it all up. I get the system to the point where
I can’t spawn anything new and I get various services and whatnot crash on
me. However, the bluescreen has not reoccurred.
How can I recreate that bluescreen?
Does anyone have any other insight as to how I should try to debug this?
Thanks!

You have to also cause paging activity such that pageable thread data
such as a user mode stack cannot be fetched from disk. If you just have
an idle system and a kernel driver sucking up non-paged pool, that is
unlikely to provoke the error.
You should use pool tags on all of your allocations in your driver, a
different tag for each code segment that allocates memory, so that when
you hit your problem again you can find out where you are springing a
leak.
