MG 2.6.5 Reweight gets killed
Dear Madgraph experts,
i'm trying to generate a computationally expansive process namely VBS production of WV pair with semileptonic final state with EFT contribution from 14 operators from SMEFTsim [1].
As the number of diagrams quickly diverges with the addition of EFT operators, i decided to run the codegen and integrate steps sampling from SM phase space and then changing process at reweight step to include all the operators.
My process definition is the following one for the first two steps ($ t t~ was added just for testing purposes)
import model SMEFTsim_
define p = u u~ d d~ s s~ c c~ b b~
define j = p
generate p p > e- ve~ j j j j $ t t~ NP=0 SMHLOOP=0 QCD=0
output emVjj_ewk_dim6 -nojpeg
Meanwhile at reweight i load the following card (just the first lines, as all the reweight points present the same syntax)
change helicity False
change rwgt_dir rwgt
change process p p > e- ve~ j j j j $ t t~ NP=1 SMHLOOP=0 QCD=0
# SM rwgt_1
launch
set SMEFT 2 0
set SMEFT 7 0
set SMEFT 9 0
set SMEFT 4 0
Both codegen and integrate run smoothly however the compilation gets killed while computing the second matrix element probably due to a system overload:

Is this behaviour expected? Do you have any solution to run the reweight step in a less expansive way, maybe trading with computation time?
Thank you, i'm at disposal if additional infos are needed.
