amplxe: Error: Ftrace is already in use.

Hi,
i am trying to run vtune amplifier 2019 to collect system-overview as - 

export NPROCS=36
export OMP_NUM_THREADS=1
mpirun -genv OMP_NUM_THREADS $OMP_NUM_THREADS -np $NPROCS  amplxe-cl -collect system-overview  -result-dir /home/puneet/run_node02_impi2019_profiler_systemoverview/profiles/attempt1_p${NPROCS}_t${OMP_NUM_THREADS}  -quiet $INSTALL_ROOT/main/wrf.exe


I had collected hpc-performance data without any issue. Afterwards , i ran aforementioned command but had to kill it (result dir was incorrect.). when i re-ran the amplxe-cl, i am getting following error messages - 
 

amplxe: Error: Ftrace is already in use. Make sure to stop previous collection first.
amplxe: Error: Ftrace is already in use. Make sure to stop previous collection first.
amplxe: Error: Ftrace is already in use. Make sure to stop previous collection first.



I have tried deleting the /home/puneet/run_node02_impi2019_profiler_systemoverview/profiles/* and i have also rebooted the node.
even then those error messages are showing up.
Please advice.
