How to find the cause of a memory leak in Windows Server 2008r2?

Question

System administration

There is an HP Proliant server with 10GB of RAM. On it: AD, dns, traffic inspector 2.0.1.720, squid.
Lately I've been losing my memory.
At the moment, rammap showed this picture after one day of system operation:


The system will work for several days and freezes tightly. The event srv 2019 appears in the event logs.
Here is the graph of the group of data collectors until the moment of freezing:

Nonpaged pool swelled to almost 8GB and the system stalled on this.
I am doing according to the article - poolmon showed 2 gluttonous tags: Nnnn and Nbuf. strings showed that they are from the netio.sys file

And I stalled, I don’t know what to do next with this.

Answer 1

Apparently really because of the traffic inspector was all this.
Updated the driver from this article, now the second day the nonpaged pool is 100mb and no longer grows
