Issue

• After upgrading Pipeline API plugin to version 2.44, the instance is less stable performance-wise. I am observing Java deadlocks at Jenkins like the folllowing example.

Environment

• CloudBees CI (CloudBees Core) on traditional platforms - Operations Center

Resolution

The issue is described in [JENKINS-65885] Deadlock in CpsFlowExecution - Jenkins Jira.

Upgrading Pipeline: API | Jenkins plugin (workflow-api) plugin to 2.45 or higher solved the issue.

Tested product/plugin versions
