I have a pipline job written by scripted pipeline with a parallel stage as below
// groovy def unitTestCodeCoverageAndSonarQubeScan(buildType) { stage("Unit Test & Code Coverage Test") { try { echo "code coverage started" sh './build.sh coverage' echo "code coverage done" publishHTML([ allowMissing : false, alwaysLinkToLastBuild: false, keepAll : true, reportDir : 'cicd/target/jacoco-aggregate-report/', reportFiles : 'index.html', reportName : 'Code-Coverage-Report', reportTitles : 'Code-Coverage-Report' ]) } catch (err) { echo "Error when test Unit Test" throw err } } } def checkStyleTest() { // some simple test } def packageServicesAndUploadToRepo() { // package something } def updateStagingEnv() { // create a mini VM } def buildMergeRequest() { def notServiceModuleList = ["cicd", "commons"] def pomXMLStr = readFile "pom.xml" def serviceList = jenkinsfile_utils.getServiceList(pomXMLStr, notServiceModuleList) def pom = readMavenPom file: "pom.xml" def projectVersion = pom.getVersion() def dockerImageTag = "${projectVersion}.${env.BUILD_ID}" def stagingPublicIP = null def tasks = [:] tasks['Unit Tests, Code Coverage And SonarQube Tests'] = { node("centos7-docker") { unitTestCodeCoverageAndSonarQubeScan("MERGE") } } tasks['Check Style Tests'] = { node("centos7-docker") { checkStyleTest() } } tasks['Package & Build Staging Docker Image'] = { packageServicesAndUploadToRepo(dockerImageTag, serviceList) } if (env.gitlabTargetBranch == env.STAGING_BRANCH) { tasks['Create Or Update Staging Env'] = { stage("Ensure Staging Environment is created") { stagingPublicIP = updateStagingEnv("create") } } } parallel tasks } return [ buildMergeRequest: this.&buildMergeRequest ]
When my jenkins pipeline is running, some time pipeline run success, sometime i get this exception:

When i set Pipeline Default Speed/Durability Level to:
Pipeline Default Speed/Durability Level: Performance-optimized
This exception gone.
According some documents, maybe i put some object which can not seriazliable to global or local variable in pipeline.
https://jenkins.io/doc/book/pipeline/syntax/#differences-from-plain-groovy
But when i see log, i can't know which object /which code block caused this exception.
