Check out this link for info on /tmp cleanup in Ubuntu: http://askubuntu.com/questions/20783/how-is-the-tmp-directory-cleaned-up
And check out this link for information on some of the work_dir's contents on a Mesos agent: http://mesos.apache.org/documentation/latest/sandbox/ The work_dir contains important application state for the Mesos agent, so it should not be placed in a location that will be automatically garbage-collected by the OS. The choice of /tmp/mesos as a default location is a bit unfortunate, and hopefully we can resolve that JIRA issue soon to change it. Ideally you should be able to leave the work_dir alone and let the Mesos agent manage it for you. In any case, I would recommend that you set the work_dir to something outside of /tmp; /var/lib/mesos is a commonly-used location. Cheers, Greg
