Dear All,
  I recently installed opal on a fedora32 laptop and the sampler feature does not work anymore. It starts fine but then hangs. The same example used not to hang in the previous versions of this OS. 
  I am attaching the stdout output and my input file (.tmpl, .in, and .data) in case somebody see an obvious mistake. The pilotTrace file clearly states the jobs (0 to 10) are all finished consistent with my scanning over 11 points. I run opal via the command
  mpirun --mca btl ^uct /home/piot/Simulations/OPAL/opal/build/src/opal
  The input file works fine alone (without attempting to do any scan). 

   Thank you for any suggestions! All the best, -- Philippe.
