Finding cause of kernel memory leak

WINDBG
1

Hi all,

I am currently investigating a kernel memory leak in a pool that has a
tag. Does Windbg have facilities for determining the cause of a
kernel memory leak? OR, are there better tools than Windbg for
determining the cause of a memory leak.

Thanks,
J

Use verifier.exe and select “Pool tracking” on your driver.

I also find Poolmon.exe (http://support.microsoft.com/kb/177415) to be
very useful once you have the correct flags turned on using either
Verifier or Gflags. It gives you live (refreshed every few seconds)
statistics, such as number of allocations and frees being made, of
each pool being tracked.
