MadGraph5Error : Histogram with run_id '0' was not found in the specified XML source.
I attach the log file and the config of the system where I'm running. I'm also experiencing the same problem in lxplus.
Thanks,
Jose

Could you check if the problem is also present when turning off PY8 parallelization?
You can do so by setting the MG5aMC option 'nb_core' to 1.
Also, could you attach the xml file that contains the DJR histograms generated by Pythia8?
It should be in:
/afs/cern. ch/work/ j/jruizalv/ public/ MC_tools/ MG5_aMC_ v2_5_1/ BBbar_13TeV/ Events/ run_01/ djrs.dat
if it was not already erased when the error occurred.
Also, given how quickly Pythia8 ran, it seems unlikely that there was not a problem there.
Could you look at the log of the Shower runs and report if you seen any mention of a problem at the end, i.e. in:
/afs/cern. ch/work/ j/jruizalv/ public/ MC_tools/ MG5_aMC_ v2_5_1/ BBbar_13TeV/ Events/ run_01/ tag_1_pythia8. log
(All the paths above are for a single run of Pythia8. The corresponding path for a parallel run of Pythia8 will be in the split_<x> directories).
Let me know
