"No stack counts found" error when profiling Sprucing throughput tests
The Sprucing throughput test cannot produce flame graph properly, see the LHCbPR page of lhcb-master-mr.5715
.
The run log implies there's an error
ERROR: No stack counts found
However, the test for lhcb-master-mr.5727
produces a flame graph, as shown in this page, but the flame graph looks strange. Seems the process was not properly profiled.
