A problem with similar stack was addressed at the end of last year. Can you please check the 2017 Update 2 release of VTune Amplifier XE (build #499904)? If the problem persists - please submit Premier Support issue with details on the system HW/OS and kernel patches if any.

Regards, Katya


Hello Katya,

If I am running into similar issues on VTune Amplifier XE 2016 (not 2017), what are the steps to resolve this issue?
