Hi, I meet a problem when running mesos-slave in the docker. Here are some zombie process in this way.
``` root 10547 19464 0 Oct25 ? 00:00:00 [docker] <defunct> root 14505 19464 0 Oct25 ? 00:00:00 [docker] <defunct> root 16069 19464 0 Oct25 ? 00:00:00 [docker] <defunct> root 19962 19464 0 Oct25 ? 00:00:00 [docker] <defunct> root 23346 19464 0 Oct25 ? 00:00:00 [docker] <defunct> root 24544 19464 0 Oct25 ? 00:00:00 [docker] <defunct> ``` And I find the zombies come from mesos-slave process: ``` pstree -p -s 10547 systemd(1)───docker-containe(19448)───mesos-slave(19464)───docker(10547) ``` The logs has been deleted by the cron job a few weeks ago, but I remember so many `Failed to shutdown socket with fd xx: Transport endpoint is not connected` in the log. I report this to the JIRA: https://issues.apache.org/jira/browse/MESOS-6615 Is there anyone saw this issue before ?
