Docker 1.9容器突然停止

我有一个托管Java应用程序的docker容器.但很多时候我看到应用程序已关闭且docker未运行.

在/var/log/daemon.log中,我只看到以下信息,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"
Oct 10 10:54:59 or4 systemd-sysctl[100591]: Overwriting earlier assignment of net/ipv4/tcp_tw_recycle in file '/etc/sysctl.d/99-sysctl.conf'.

以下是docker logs< container id>的输出.

下面是docker文件.

AAAA,XXXX等是占位符.

有人可以解释一下可能出现的问题,我该如何调试此问题？

环境：-

> Docker 1.9
> Debian 8 64位

最佳答案

问题不在于Docker或其任何配置.外部进程定期重新启动docker,而docker又重新启动了docker中运行的orchestrator进程.
