Actually Dan, in the 'workspace' area of at least one node I found :-

$JENKINS_HOME/jenkins-slave/workspace/trafficcontrol-PR_ws-space*

The size averaged around 350MB each, not big in itself but when you
mulitply that by 6750
such directories that make over 100GB.

As such, I'd like to understand what these directories are, how they are
being made and
what the job configs are.

Thanks
