> When first setting a mesos cluster up, it is possible to get into a state where your slaves are constantly re-registering. This happens because the slave pid is not reachable from the master.
> Currently, the master logs make it pretty tough to figure out that this is the problem that is occurring. It would be fantastic if there was a better explanation in the logs, something like:
>     Unable to connect to slave X at x.x.x.x:5051. Please make sure that host is reachable from your master.
