Issue
-
Jenkins UI is running incredibly slow
-
Pipeline Stage View UI is not responding or running slowly
-
Pipeline Builds are never finishing
-
Loops are defined in the slow Pipeline.
Environment
-
CloudBees CI (CloudBees Core) on modern cloud platforms - Managed controller
-
CloudBees CI (CloudBees Core) on traditional platforms - Client controller
-
CloudBees Jenkins Enterprise - Managed controller
Resolution
Try not to use use infinite while loops inside of Pipeline code.
A better alternative would be a Retry + Sleep blocks.
This will eliminate the possibility of an endless cycle of a build because it will stop trying after a certain number of attempts. Additionally it ensures that a failure is recorded if the the looped step is unsuccessful.
