Toke , SeTd( paged and non paged ) keep depleting with driver installed

Hi all ,

I have inherited a driver and I am testing it. When I run longevity tests on the system with the driver installed the Toke and Setd keep increasing when I check with poolmon with d switch to see pools with non free allocations.

My driver is sort of a hello world project with very simple logic. I am going nowhere close to security tokens!

Have you ever seen this ? what would be the reason for this.

Just to be clear, you’ve checked these tags without your driver installed?

Absolutely without the driver the Toke tag remains static forever.

Just found a peice of nasty code that calls - ZwOpenThreadToken and never closes the handle this looks looks like the culprit. In process of compiling and reinstalling let you know if it was a quick one to resolve!!
