Bug Description
Hi,
I'm trying to generate a matched jet sample using pythia8 and MG 2.5.3, but I'm getting the following error:
Command "generate_events run_01" interrupted with error:
InvalidCmd : Pythia8 shower failed since it did not accept any event from the MG5aMC event file.
I'm doing the following for the generation:
generate p p > z, z > e+ e- @0
add process p p > z j, z > e+ e- @1
add process p p > z j j, z > e+ e- @2
output ~/mgoutput2/
launch
shower=pythia8
detector=delphes
set run_card ickkw 1
set run_card auto_ptj_mjj True
set run_card xqcut 20
set pythia8_card JetMatching:qCut 30
The same process with MG 2.3.3 and pythia 6 works fine.
I'm attaching the end of one of the log files (Events/
Thanks in advance,
Nicolas.

Could you try reshowering your events with Pythia8 but turning off the
parallelization handled by MG5aMC. You can do so with
./bin/mg5 zjj_matched_ MG253 -i
launch ~/mgoutput2/
set nb_core 1
shower pythia8 run_01 -f
Make sure that no multiple jobs are created this time. Let me know if it
works or if you face a similar error again (in which case it would be good
to attach the corresponding PY8 log file again).
