A few days ago I was troubleshooting some strange problems on a Citrix Server. After some investigation (I will write about that later) it was clear to me that there was a shortage of System Page Table Entries (PTE’s). Using perfmon you can see how many free System PTE’s are available:
Any value below 5000 is not good, values below 2000 are critical. In my case it wasn’t possible to view processes with Task Manager anymore.
Next I used WinDbg and attached to the Kernel (you can do that with File | Kernel Debug | Local | OK) and issued the !vm command:
WinDbg shows us a warning that a lot of PTE allocations have failed, we can also see that there’s enough Paged Pool and Non Paged Pool available.
So how do we find the guilty driver (usually it’s a driver)? (more…)

I have found and tested some new functionalities which I will add to SasLibEx:
