我有一个自定义的systemd“.service”文件，如下所示：
[Unit]
Description=MyStuff
After=syslog.target
After=network.target
After=local-fs.target
After=remote-fs.target
[Service]
Type=simple
User=root
Group=root
ExecStart=/usr/local/MyStuff/start
ExecReload=/bin/kill $MAINPID && /usr/bin/cat /var/run/MyStuff.pid | /usr/bin/xargs --no-run-if-empty /bin/kill
ExecStop=/bin/kill $MAINPID && /usr/bin/cat /var/run/MyStuff.pid | /usr/bin/xargs --no-run-if-empty /bin/kill
ExecStartPost=/usr/local/MyStuff/after_start.sh
PIDFile=/var/run/MyStuff.pid
#RemainAfterExit=yes
TimeoutSec=300
Restart=always
RestartSec=10
[Install]
WantedBy=multi-user.target
几分钟前它运作良好。 systemctl stop MyStuff以这种方式挂起：
[root@Live-1 ffmpeg]# systemctl status WowzaStreamingEngine

我知道那里有错误报道。那不是问题;我不是在问这些错误。问题是： systemd / systemctl在该状态下挂起，我无法执行启动/停止/重启动作，因为它们都会一直等待。
我需要知道的是绕过那个州。这次我只是重新启动了服务器，因为它是开发环境。但我不能只是这样处理生产。
所以：当systemd / systemctl以这种方式挂起时，为了在不重新启动服务器的情况下从此状态恢复服务，我该怎么办？
提前致谢。
