• Jenkins UI is unresponsive and recovers after several minutes

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

• CloudBees Jenkins Platform - Client controller

• CloudBees Jenkins Distribution

• Jenkins LTS

• Promoted Builds Plugin < 2.29.1

Resolution

When using the DownstreamPassCondition of the Promoted Build Plugin - i.e. the option When the following downstream projects build successfully - Jenkins looks for a match among all items.
This is done via a RunListener.
Prior to version 2.29.1 of the plugin, the implementation of this Listener is terribly inefficient.
The fix is to update the Promoted Build Plugin to 2.29.1+.

See JENKINS-37368 for more information.
