一个服务死了，我只知道有什么东西被打破了。 我敢肯定，自从带来systemd的Debian 8升级以来，这种情况已经发生了，尽pipe我并不完全确定systemd是应该受到指责的。
我不确定之前的init是否刚刚重新启动了死机，而systemd没有启动。
他们的症状是systemctl status foo.service显示像active（exited）之类的东西。
有没有办法注意到系统pipe理服务中状态的改变？ 和/或让它尝试重新启动几次？
（我是systemd新手。）
这是一个例子：Stunnel已经停止了。 这是我做了什么让它再次工作：
root@server:/root# systemctl status stunnel4 ● stunnel4.service - LSB: Start or stop stunnel 4.x (SSL tunnel for network daemons) Loaded: loaded (/etc/init.d/stunnel4) Active: active (exited) since Sun 2016-05-01 07:03:54 BST; 2 days ago Process: 13443 ExecStop=/etc/init.d/stunnel4 stop (code=exited, status=0/SUCCESS) Process: 13455 ExecStart=/etc/init.d/stunnel4 start (code=exited, status=0/SUCCESS) Warning: Journal has been rotated since unit was started.

我能find的唯一日志似乎是重新启动：
syslog.2.gz:May 1 07:03:54 pap1 stunnel4[13443]: Stopping SSL tunnels: [stopped: /etc/stunnel/stunnel.conf] stunnel. syslog.2.gz:May 1 07:03:54 pap1 stunnel4[13455]: Starting SSL tunnels: [Already running: /etc/stunnel/stunnel.conf] stunnel.
看起来像失败了 我不知道为什么重新启动（系统上的其他问题 ），也不是为什么失败。
