cpu_decoding test getting stuck in case you do not use rigth version of ParamFiles
the test decode_no_ut_output
was hanging forever for me recently. It happened to be due to ParamFiles not being recent enough. One gets this in the log :
"trException: Two Track MVA model file /cvmfs/lhcb.cern.ch/lib/lhcb/PARAM/ParamFiles/v8r43/data/CaloPID/electron_mva_AllenFeb2024.json does not exist
but the exception is not caught, thus the thread having it exists and all others are pending forever in zmq, waiting for it.
