Description

When upgrading from 0.19.1 to 0.20.0, any slaves started with the standard deimos setup fail hard on startup. The following command spits out about 20.000 errors before core dumping:

/etc/mesos-slave# /usr/local/sbin/mesos-slave --master=zk://localhost:2181/mesos --port=5051 --log_dir=/var/log/mesos --ip=172.17.8.101 --work_dir=/var/lib/mesos --isolation=external --containerizer_path=/usr/local/bin/deimos

output:
