Please see here - https://issues.jenkins.io/browse/JENKINS-65873?focusedCommentId=424033&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-424033 and ticket in general. This issue only happens when there is a git checkout stage in the pipeline. One suggestion here - https://github.com/jenkinsci/remoting/pull/505#issuecomment-1062281877 - is to downgrade the git client plugin to 3.7.0. It seems that the suspicion is somewhere on the git side of things. Any ideas, suggestions, things we can do to help debug ?
