Only when user not logged in to the Ubuntu slave: java.io.IOException: Failed to mkdirs

[Pasi]

Hi guys,

I've run into a weird issue, for quite some time some of my jobs have failed during the weekends, and I have now understood that it happens because usually I'm not logged in to the slave executing the jobs during weekends. Today morning this also happened as I was logged in during the whole week but just for the fun of it I logged out to see if my idea is valid and sure enough, the jobs started to fail right after logging out of the slave.

This is the failure:

Jenkins master is v1.466.2 running on Ubuntu 12.04.2 LTS (64-bit), installed via .deb package, Java version "1.7.0_17". Slave running on Ubuntu 12.04.2 LTS (32-bit), started via JNLP (using command: screen -d -m java -jar ...), Java version "1.7.0_17".

How could I try fix this issue?

Thanks!
