IRP tag nonpaged pool memory Leak

[Stephen Melis]

Hoping someone can help.

I've got WinXPSP2 installed, with all latest update and patches

I have a nonpaged pool memory leak for the Irp tag, (according to poolmon
from the resource kit) trouble is I cannot remember for how long this has
been occurring but I know its been few months and I've manage to track it
down to this location. It is leaking at a rate of about 150Mbytes per day.
This means I must reboot every day or I get a BSOD after about 48 hours

I've been trying to track down the culprit program/driver for the leak but
with no luck.

The pool leak occurs in safe mode as well as normal mode. I've gone and
disabled all non Microsoft drivers in save mode but still the leak occurs.

What can I do now to find out which program is writing to that Irp tag in
the Pool.

I hope some one can give me a pointer in a direction that may help

Many thanks in advance,

Steve

Did you try Microsoft's Driver Verifier to see if it could identify the
driver at fault?

Hi John,

Yes, I've tried Verifier now for about 24 hours it but it didn't identify a
faulty driver or a leaky driver, every driver seemed to free the memory it
allocated but yet the Irp nonpaged pool keeps growing a rate of about
1.2Kbytes per second.

Verifier kept on telling me to add more memory, but I've got 4Gbyte memory
on the PC and windows recognizes all of it.

Would you have any other suggestions?

Thanks in advance,

Steve
