SecAst：在守护程序模式下提前退出

代D：

这是构buildsecast-1.0.4.0-x86_64-ub12时出现的一个新问题，在之前的版本secast-1.0.1.0-x86_64-ub12中没有发生。

当secast作为服务运行（服务secast start）或者在守护进程模式（/ usr / local / secast / secast）下从命令行启动时，几秒钟后退出，没有任何明显的原因。 启动以前版本的secast时，它将按预期保持运行状态，直到通过用户操作明确closures为止。

在前台运行secast的最新版本（/ usr / local / secast / secast -f）时，这个问题并不明显。

• 在Linux中安装操作系统程序
• MacOS优胜美地：在/ Library / LaunchDaemon中设置PATHvariables是否工作？
• 如何在后台发送一组命令
• 如何检查守护进程是否正在运行
• 未使用软件包pipe理器安装的软件的适当系统单元位置

这里是/ var / log / secast文件的内容（注意“General，Received shutdown request via HUP”），表示在守护进程模式下运行时的问题：

注意：/ usr / local / secast / secast在一次会话期间确实设法保持一次尝试，但是在重新启动计算机时，问题又回来了。

这是否需要代码修复，因为以前的版本在这方面似乎按预期工作？
