VTune hangs Bottom-up

$

I am doing VTune Basic Hotspot runs on 256 threads (KNL), 180 seconds runtime. (V17.0u4, on Linux)

When I finally get to the Summary page (long time on KNL), I can then either click on one of the different tabs, or click on a highlighted link of the handful of most active routines. When I click on Bottom-up tab, this often never completes. If instead I click on a highlighted link of the handful of most active routines it often succeeds. (although it is hanging as I type this). The Bottom-up window displays the Function call stack and information, but is disabled (greyed out). IOW I cannot brows the Function/Call stack.

If during Hang, I click on Top-down Tree tab, it will break out of the hang, and display the tree. Browsing via top-down is less convenient than using the bottom-up.
