Jenkins build fails with Cannot contact XXXXXXXXXXXX: java.lang.InterruptedException
I monitored the slave stats and figured out that the slave was under heavy load like 1200 and climbing. The slaves build a lot of docker images. The load was due to the fact that the save was I/O bound. The docker volume /var/lib/docker and workspace were EBS and EFS mounts respectively. Upgrading the linux kernel and changing the docker volume to Overlay2 solved the issue.
