Problem: Skipped Stack Frames

Intel® VTune™ Amplifier displays [Skipped stack frame(s)] in the grid panes.

Cause

VTune Amplifier did not unwind the stack to reduce data collection overhead, and failed to resolve the stack heuristically.

Solution

You may collect deeper stacks by creating a custom event-based sampling analysis and increasing the Stack size option value in bytes (-stack-size option in CLI), though beware that this also increases the collection overhead.
