Hi all.
I saw this on appeared in many cases but I did not see any resolution.
I am working with 2013 update 8, collecting on a remote machine and copying the results for the GUI stuff.
I am trying to run lightweight hotspots analysis with stacks and can not.
working without stacks is successful:
This is why I think all my drivers are working fine.
# ./amplxe-cl -collect lightweight-hotspots --duration 10
amplxe: Warning: On some systems based on the Intel microarchitecture code name Nehalem / Westmere with C-states enabled, this analysis type may cause system hanging due to a known hardware issue (see errata AAJ134 in http://download.intel.com/design/processor/specupdt/320836.pdf). To avoid this situation, disable all "Cn(ACPI Cn) report to OS" BIOS options before sampling with VTune Amplifier on such systems.

however trying to add stack collection causes this db issue:
first I can see that this makes me add a pid to attach to (why?, can't I do this system wide?)
when adding the pid and the request for stacks I get the failures and the .tb6 file is not generated.
When I try to open this in the GUI it fails.
# ./amplxe-cl -collect lightweight-hotspots --duration 10 -knob enable-stack=true -target-pid 3594

Sorry for late answer.
Regarding the results of the discussion I think that database error issue can be solved by VTune devs and we only can speculate about the possible culprit.
