we don't see the error in slc7 amd64 gcc900 and other architectures, so perhaps it is just a temporary problem

this is the second time I see this error being revived in a PR Jenkins test:

jfernan2 · 2020-11-26T11:55:41Z

What I am not sure if this is related to the SiStripRawToDigiModule:siStripDigis Warning before (it seems not since that warning is present in several other unit Tests) or to the beam_dqm_sourceclient itself

I have just tried to reproduce it using exactly same settings as in #32036 but failed, however perhaps it makes sense to reopen this issue since it seems to be there

FYI: @gennai @francescobrivio

mmusich · 2020-11-26T14:37:40Z

@jfernan2
just a clarification on this

What I am not sure if this is related to the SiStripRawToDigiModule:siStripDigis Warning

the warning comes from the Strip unpacker and just signals there is one or more FED(-s) out of DAQ [1] (1800 is the number of times the same warning is emitted) .
Given there are many SiStrip FEDs out of DAQ in the run chosen for the unit test 334393 [2] it is not surprising to see them.
Moreover we are running the Strip unpacker in several other online clients (including the Strip online one) without problem, so I really tend to exclude a problem with that.

jfernan2 · 2020-11-26T14:40:21Z

Thanks @mmusich
Yeah, indeed it is not related to SiStripRawToDigiModule:siStripDigis and not even reproducible (I tried offline 10 times so far... :-P )

jfernan2 · 2020-11-26T14:52:00Z

Another one example: #27983 (comment)
May it be correlated to the switch to CMSSW_11_3_X in the milestone?

I would exclude that 11_3_X can cause this problem.

Googling "Fatal system signal has occurred during exit" I've found a @makortel issue #32045

silviodonato · 2020-11-26T16:27:45Z

The same error was seen here #31190 (comment)

silviodonato · 2020-11-26T18:46:41Z

The error Fatal system signal has occurred during exit is always reproducible on the ASAN release.
This is the minimal code reproducing the error

import FWCore.ParameterSet.Config as cms

process = cms.Process("BeamMonitor")

process.source = cms.Source("PoolSource",
    eventsToProcess = cms.untracked.VEventRange("334393:1:16049-334393:1:16407", "334393:2:32684-334393:2:33028"),
    fileNames = cms.untracked.vstring(
        '/store/express/Commissioning2019/ExpressCosmics/FEVT/Express-v1/000/334/393/00000/D0F052ED-9CA5-F547-BA73-2AA370D51AE8.root',
    ),
)

process.scalersRawToDigi = cms.EDProducer("ScalersRawToDigi",
    mightGet = cms.optional.untracked.vstring,
    scalersInputTag = cms.InputTag("rawDataCollector")
)

process.OnlineDBOutputService = cms.Service("OnlineDBOutputService",
    DBParameters = cms.PSet(
        authenticationPath = cms.untracked.string('.'),
        messageLevel = cms.untracked.int32(0)
    ),
    autoCommit = cms.untracked.bool(True),
    connect = cms.string('sqlite_file:BeamSpotOnlineLegacy.db'),
    jobName = cms.untracked.string('BeamSpotOnlineLegacyTest'),
    lastLumiFile = cms.untracked.string(''),
    latency = cms.untracked.uint32(2),
    preLoadConnectionString = cms.untracked.string('sqlite_file:BeamSpotOnlineLegacy.db'),
    runNumber = cms.untracked.uint64(334393),
    saveLogsOnDB = cms.untracked.bool(False),
    toPut = cms.VPSet(cms.PSet(
        onlyAppendUpdatePolicy = cms.untracked.bool(True),
        record = cms.string('BeamSpotOnlineLegacyObjectsRcd'),
        tag = cms.string('BSOnlineLegacy_tag'),
        timetype = cms.untracked.string('Lumi')
    )),
    writeTransactionDelay = cms.untracked.uint32(0)
)


process.p = cms.Path(process.scalersRawToDigi)

It runs without errors in CMSSW_11_2_X_2020-11-25-2300.

It crashes in CMSSW_11_2_ASAN_X_2020-11-25-2300 with

Fatal system signal has occurred during exit

@silviodonato Does the crash in ASAN have any information in addition to the "Fatal system signal during exit"? (if it does, could you paste it here?)

No, there is no additional information (see https://cmssdt.cern.ch/SDT/cgi-bin/logreader/slc7_amd64_gcc820/CMSSW_11_2_ASAN_X_2020-11-25-2300/unitTestLogs/DQM/Integration#/51)
