Steven Murdoch commented on JENKINS-9589:
-----------------------------------------
I haven't found a workaround for this, and it is still causing a problem. What
I ended up doing was having a cron job restart the Jenkins build master every
night. It's far from ideal but at least keeps the problem under control.
