4 years ago any inputs on the above issue ?
On one of out tests setups we are experiencing bugcheck 7F EXCEPTION_DOUBLE_FAULT as shown below. The user mode context of the faulting thread is our .net GUI application i.e. when it is in the process of being terminated via script (using pskill). The crash is random in that sometimes pskill on the process does not bugcheck the system. Earlier I came across this post which looks similar to the issue we are facing.

Since this is an automation setup I am nor sure exactly what is the UI state of the application. Presumably there are several error popups which could be active at the point when pskill is initiated on our process. Just wanted to understand if there's any way in which we could circumvent this issue ? With that I am assuming that generally and under no circumstance should UM code be able to trigger a KM bugcheck.
The OS is Windows Server 2009 standard edition and is up to date with the latest patchs as of this writing. Earlier there was wdfilter,sys also in the call stack which I disable via local group policy. But the crash persists even without wdfilter in the call stack.
