I have hundreds of pipeline jobs that are showing queued against the master, but not assigned to an executor. If I check each job, all the jobs are already completed (success or failures). They're just stuck. Restarting the master doesn't seem to help.
Job logs all show evidence of trying to resume the job after master restart:
[Pipeline] End of Pipeline Resuming build at Tue Feb 06 01:27:30 UTC 2018 after Jenkins restart [Pipeline] End of Pipeline
There are a ton of entries in org.jenkinsci.plugins.workflow.flow.FlowExecutionList.xml – are these the stuck jobs? I tried clearing them and bouncing the master, but they 'come back'
Eventually it seems like the master gets overloaded with these stuck jobs, and stops processing or dispatching jobs to slaves.
Attached a copy-paste of the /threadDump page, which shows both the list of jobs queued against the master, and all the threads associated. Note, there are a ton of these threads:

It seems like there should be a check – Jenkins should never attempt to resume a completed job. Also seems like resume should timeout after some low threshold, 300sec default or something.

All pipelines jobs are being started on master that caused a server load.
