我有一个托管 Java 应用程序的 Docker 容器。但我多次看到应用程序关闭，Docker 未运行。
我/var/log/daemon.log只看到以下信息，没有错误
Oct 10 10:54:58 or4 docker[18366]: time="2016-10-10T10:54:58.875341257+05:30" level=info msg="POST /v1.21/containers/c1a64d308f45/stop?t=10"

以下是输出docker logs <container id>

AAAA、XXXX、 等是占位符。
有人可以向我解释一下可能出了什么问题以及我该如何调试这个问题吗？
环境：-
- Docker 1.9
- Debian 8 64 位
答案1
问题不在于 Docker 或其任何配置。外部进程定期重启 Docker，而 Docker 又会重启 Docker 内部运行的 Orchestrator 进程。
