Running systematics gives error at large number of events

Hi,

I want to use a specific PDF during the generation of pp>hh [QCD] events. If I launch MadGraph like this, it works fine:

./bin/mg5_aMC mg5_customconfiguration.txt

Where mg5_customconfiguration.txt contains:
"""""
import model ./models/loop_sm
generate p p > h h [QCD]
output pp2hh_loopsm
launch
shower=Pythia8
detector=Delphes
set nevents 100
set pdlabel lhapdf
set lhaid 264000
""""""

However, when I try to increase the number of events (nevents) in mg5_customconfiguration.txt to 10000, it returns an error when starting the systematics:
