Problem with Intel Trace Collector

I'm trying to use for the first time the intel trace collector on a cluster machine (with the intel xe 2013 and the itac 8.1.2.033).

I built my program in the standard production mode and in the bash script submitted to the PBS scheduler there were the following commands:

#PBS -l select=14:ncpus=16:mem=120gb:mpiprocs=16

module load intel/cs-xe-2013

source [path]/cs-xe-2013/none/itac/8.1.2.033/bin/itacvars.sh

mpirun -trace [path]/my_program [arguments]

Reading the log I saw that the program reached its end 4 hours ago, but the job is still running: a .prot file with 17064 bytes and a .sft file with 0 byte have been written.

Did I do something wrong?

Thank you in advance
