Hello,

Sometimes some of our team project pipeline jobs are getting stuck (screentshot provided) on

"Notify commit build result"

step. Time to finish job shows "null" and in logs report such kind of messages:

Sep 7 07:50:07 jenkins-1 nice[21775]: INFO: Skipping job "blablabla" with type org.jenkinsci.plugins.workflow.multibranch.WorkflowMultiBranchProject
Sep 7 07:50:44 jenkins-1 nice[21775]: WARNING: Failed to load Owner[blablabla/blablabla/initial/13:blablabla/blablabla/initial #13]. Unregistering
Sep 7 07:50:44 jenkins-1 nice[21775]: java.io.IOException: blablabla/blablabla/initial #13 did not yet start

This can be fixed by manually delete this job (build number) on server and restarting Jenkins.

Jenkins version (running not in container, starting as a .war via service): 2.60.3
OS: Ubuntu 16.04 x64
Pipeline multibranch plugin version: 2.16
JRE: 1.8.0_121
Jenkins agents: connected via ssh

Please note, that all our build numbers were somehow reseted for all builds.
