Error message : An unexpected sequence of events was found

Hi,

With a brand new machine (W10 64 bits, version 1703), whenever I carry out a basic hotspot analysis, I have the same error message at the end :

"Accurate CPU time detection was disabled. When processing data from NT Kernel Logger, an unexpected sequence of events was found."

I don't see anything in the Troubleshooting sections for this case, I ran all my analysis in Administrator mode. I use VTune Amplifier 2017 Update 4.

Best regards.

Alain.

Hi Alain,

Please refer https://software.intel.com/en-us/node/596777:

VTune Amplifier requires the Microsoft* NT Kernel Logger to capture precise CPU time data. The NT Kernel Logger is a system-wide resource which cannot be shared by different processes. Other tools, such as the Xperf utility of the Windows* Performance Tools Kit may use the NT Kernel Logger at the same time.

You may check what is using the logger when VTune is running. If you still failed to finalize the results, you can zip it and submit via Online Service Center (supporttickets.intel.com/)

Thanks
