When zookeeper starts, you may see an error like this in the logs:\r\n\r\n```\r\nNov 19 03:02:36 resching-control-01.cisco.com systemd[1]: Starting zookeeper...\r\nNov 19 03:03:03 resching-control-01.cisco.com docker[10779]: Error response from daemon: Cannot destroy container zookeeper: Driver devicemapper failed to remove init filesystem dbcbaa47a36dc59fdbaa8dd9051faaf00ac099a924de11ac222b804ba576ff5a-init: Device is Busy\r\nNov 19 03:03:03 resching-control-01.cisco.com docker[10779]: Error: failed to remove containers: [zookeeper]\r\nNov 19 03:03:04 resching-control-01.cisco.com docker[10840]: Trying to pull repository docker.io/ciscocloud/zookeeper ... 0.3: Pulling from ciscocloud/zookeeper\r\n```\r\n\r\nNote that this causes an almost 30 second delay when starting up zookeeper and sometimes results in zookeeper not being available by the time the `zookeeper-wait-for-listen.sh` times out (60 seconds).\r\n\r\n"}}
