BranchIndexing deadlock with health check - Jenkins slowness

Issue Type:	Bug
Assignee:	Lucie Votypkova
Components:	disk-usage-plugin, pipeline-multibranch-defaults-plugin, scm2job-plugin
Created:	2019-01-25 13:48
Priority:	Minor
Reporter:	Radhika KV

Jenkins becomes very slow with the below message in the health-checker.log

The branch indexing for My-Multi-Branch-SNAPSHOT succeeds without issues most of the time. But at times, it gets into a deadlock like below.

Over time, jenkins completes hangs up and we end up restarting to restore the server.

Requesting help in identifying the root cause of the issue and solution for the same.

Jenkins version: 2.7.4

Branch indexing log: It hangs forever
