TSX sampling of aborts fails

I was able to collect data of TSX sampling (option '1. Transactionl success') - but if I select option '2. Aborts' Vtune gives me an error:

Error 0x40000024 (No data) no data is collected ...

I use the same binary (application using TSX) for both cases. Why is Vtune unable to collect data for TSX aborts?

probably there were too few aborts happened (VTune record data only once per X events - this is sampling). Try to decrease the "sample after value" or make your workload run longer.
