[help] Memroy leak in XP SP2

Archived from groups: microsoft.public.windowsxp.help_and_support (More info?)

I have some trobles on some new computer with Windows XP SP2.
After a few days of functioning (the PC are up 24h/day) i have the
event id 2019 with SRV source: "The server was unable to allocate from
the system nonpaged pool because the pool was empty."

So i suspect a memory leak, and i startes monitoring a PC with Poolmon,
to find the culprit tag.

After a day of monitoring, i found the tag "Ifs" is allocating a lot of
non-paged memory pools.

But i don'y understand what process or driver is associated to that
tag.
How can i find the culprit process or driver?

The PC is an IBM Thinkcentre A51p, with XP SP2 provided by vendor and
pre-installed on the machine.
