> In the Docker container (`src/docker/executor`), we call `docker inspect` right after
`docker run` ([https://github.com/apache/mesos/blob/1.6.0/src/docker/executor.cpp#L230:L242),] there
is a small chance for `docker inspect` to return an incomplete result which does not contain
the Docker container ID, so we will see an error like below:
> {code:java}
> E0830 00:09:37.303499 2428 executor.cpp:385] Failed to inspect container 'mesos-eaa4f455-0a2c-47ff-bf98-8bd0ad243740':
Unable to create container: Unable to find Id in container
> {code}
> If that happens, Docker executor will not send `TASK_RUNNING` status update, so the task
will be stuck at `TASK_STARTING`.
