我创建了两个单独的 Play！框架 2.1.0 应用程序： afront-end和 a cms，应该在不同的端口上运行。这些项目共享大量代码，并连接到同一个数据库（使用相同的凭据）。
我已经用play dist. 我可以启动任何一个（front-end/start -Dhttp.port=1234 &），它会创建一个 PID 文件并按预期运行。
但是，当我启动另一个项目 ( back-end/start -Dhttp.port=5678 &) 时，我看到该项目开始了，但第一个项目被杀死了！
这两个项目在彼此独立时都可以正常工作，而且我启动它们的顺序似乎没有任何区别。
我已经改变了，application secret所以他们是不同的。
请注意，第一个进程在尝试在浏览器中访问它时会被杀死（在验证第二个进程是否正常工作之后），但它的 PID 文件永远不会被删除。
编辑：如下所示，我在两个终端中运行了这两个应用程序，这就是发生的事情：

第二个过程：

^C
（调试输出完全一样，这里省略）
我多次尝试了这个过程，结果有一些细微的变化：当等待第一个应用程序在启动第二个应用程序之前达到“侦听 HTTP”时，第二个应用程序从未通过“数据库 [默认] 连接”。
