Subject Re: Changing mesos slave configuration
Date Wed, 23 Sep 2015 12:11:40 GMT
Are you using systemd? There is a known issue with slave recovery on
systemd. I'm on mobile or I would link you to the last thread around this
but there is a line you can add to the config that is supposed to fix it.
Whether it will fix it is another matter. I am fighting this issue at work
myself.
