doesn’t have label

[Alok Dubey]

We recently got into an issue where Jenkins master is failed to schedule/distribute builds even though a lot of build agents are sitting idle. We noticed this problem with both ec2 fleet and ec2 (on-demands) plugins. 

Most of the jobs are stuck in the queue with the following message but nodes with the required labels are up in the UI. 

Anyone has experienced similar behavior? Any suggestions to fix this? Thanks.

I've sometimes seen something like that when working with the static agents that I have connected to my controller.  I workaround the problem by adding a "junk" label to any one of the agents.  After saving the junk label, I configure the agent again to remove the "junk" label and that seems to cause jobs to again recognize agent labels.

Possibly, though I've used my workaround for many months and that issue was only introduced in in Jenkins 2.426.
