GEN crash at lumi-boundary change in 10_3 HIN campaign

Not sure if it's related to https://github.com/cms-sw/cmssw/issues/25708

In the new HIN campaign (with CMSSW_10_3), there is the failure in production, e.g. https://cms-unified.web.cern.ch/cms-unified/report/cmsunified_task_HIN-HINPbPbAutumn18pLHE-00005__v1_T_200429_213517_9970

I've checked, and see that the crash on Module: Pythia8HadronizerFilter:generator (crashed) happens at the LS boundary.

How to reproduce the issue: One can use https://cms-pdmv.cern.ch/mcm/public/restapi/requests/get_test/PPD-HINPbPbAutumn18GS-00005 i.e.

(1) checkout CMSSW_10_3_2 and grid environment

(2) Checkout GEN fragment curl -s --insecure https://cms-pdmv.cern.ch/mcm/public/restapi/requests/get_fragment/PPD-HINPbPbAutumn18GS-00005 --retry 2 --create-dirs -o Configuration/GenProduction/python/PPD-HINPbPbAutumn18GS-00005-fragment.py

(3) Here is the cmsDriver, skipping 90 events. cmsDriver.py Configuration/GenProduction/python/PPD-HINPbPbAutumn18GS-00005-fragment.py --filein "dbs:/Ups1SMMCoh_5p02TeV_STARlight_PPDTest/HINPbPbAutumn18pLHE-pilot_103X_upgrade2018_realistic_HI_v11-v1/LHE" --fileout file:PPD-HINPbPbAutumn18GS-00005.root --mc --eventcontent RAWSIM --no_exec --datatier GEN-SIM --conditions 103X_upgrade2018_realistic_HI_v11 --beamspot RealisticPbPbCollision2018 --step GEN,SIM --nThreads 1 --scenario HeavyIons --geometry DB:Extended --era Run2_2018_pp_on_AA --python_filename PPD-HINPbPbAutumn18GS-00005_1_cfg.py --no_exec --customise Configuration/DataProcessing/Utils.addMonitoring -n 500 --customise_commands "process.source.skipEvents=cms.untracked.uint32(90)"

How this request passed McM validation: When pLHE+GS are validated together, McM submits jobs to condor without setting no. of events per LS. Example: https://cms-pdmv.cern.ch/mcm/public/restapi/chained_requests/get_test/PPD-chain_HINPbPbAutumn18pLHE_flowHINPbPbAutumn18GS_flowHINPbPbAutumn18DRNoPU-00002

    -sanchez Maybe we just need https://github.com/cms-sw/cmssw/pull/25850 to 10_3 as a workaround.

    Backport makes the GEN-SIM step works as expected. Here is the PR: https://github.com/cms-sw/cmssw/pull/30073

    Thanks.
