I ran low on disk so jenkins took my master node offline.
I tidied up freeing space, and restarted jenkins.
Build started.
After all steps and actions, jenkins sez:
Looks like the node went offline during the build. Check the slave log for the details.FATAL: /build/jenkins/slave-null.log (No such file or directory)
