[RESOLVED] Win2008R2 SP1: STOP 0xAB in nt!MiCheckSessionPoolAllocations

Artikel
08/09/2011

Status: Resolved.

Update 110809: As part of the HTP11-10 releases, we are releasing KB2585233, which addresses a problem that results in STOP 0xAB errors. Do note that not all of these errors have the same cause. In general, have a look at outdated video drivers, printer drivers, and if applicable, update your Citrix components as well. Then, implement the latest win32k.sys hotfix, and if the issue remains, create a case with us.

We now have two customers hitting a STOP 0xAB, similar to the STOPs we saw quite some time ago, after Win2003SP1. For one of the customers, the dump shows:

To see the leaking pooltags, use:

5: kd> !poolused 8

If you encounter these STOPs on your machine(s) too, let me know!
