What it says in the topic. This appears to be essentially 100% reproducible, but it took me a while to figure out what's going on. It does not occur when the VTSS service is stopped (e.g. "net stop vtss").
I don't have a recent minidump (that last crash didn't produce one for some reason). Running WinDbg "!analyze -v" on an older minidump reports an "EXCEPTION_CODE: (NTSTATUS) 0xc0000094 - {EXCEPTION} Integer division by zero" in vtss.sys.
Given that uptime seems to be a factor in this, I would hazard a guess that some time calculation inside vtss.sys is either overflowing or underflowing.

This is a known issue in old product (but I never experienced this issue:-( ), vtss caused an exception in kernel module. I don't know if there was IRQs of vtss conflicted with others, or other software was using PMU resource, or other real-time DBG tool was installed.
One way is to stop vtss service, but user-mode data collections of VTune Amplifier still can be used. Or try to install VTune Amplifier XE 2016 in other machine, where has less 3rd-party software installed.

Hi Fabian,
Do you observe the same behaviour with the VTune Amplifier XE 2016 Update 1 version?
If yes - what is your hardware and operating system version?

Hi,
Please specify what builds of VTune 2016 and Windows 10 you are using?
There is a known issue of VTSS on Windows 10 November update (1511). It will be addressed in future Update 2 release of VTune Amplifier XE 2016 coming soon.
In the VTune Amplifier XE 2016 Update 1 - VTSS should work on Windows 10 original release (build 10240).

>>>EXCEPTION_CODE: (NTSTATUS) 0xc0000094 - {EXCEPTION} Integer division by zero" in vtss.sys.
I would hazard a guess that some time calculation inside vtss.sys is either overflowing or underflowing.>>>
I suspect also overflow/underflow situation. What is very annoying is the occurrence of aferomentioned exception in kernel mode, in such a case BugCheck will follow immediately.

Hello All,
An update on the two different issues with vtss.sys reported in this thread:
1. Windows 10 "1511" update support by vtss.sys - is available in the VTune Amplifier XE 2016 Update 2 since Dec 24th 2015. If your support period was valid at that time - you are eligible to upgrade to the release.
NOTE: there is a remaining known limitation with vtss.sys on Windows* 10 OS - profiling of video playback applications may fail in some cases. The root cause is under investigation. If you experience such error - please submit Intel Premier Support issue with minudump attached.
2. "{EXCEPTION} Integer division by zero" error in vtss.sys on Windows* 7 and 8 - potential fix will be released in future versions of VTune later this year. There is a vtss.sys patch which we can provide to VTune customers for early verification. If you are interested in the fix testing - please submit Intel Premier Support issue with these details to receive the patch and instructions on how to apply it.
Regards, Katya
