软件：
马拉松1.1.1，mesos 0.28.1
问题：
有时，我们注意到从mesos到marathon提供的资源非常少，这会导致应用程序陷入“等待”状态。在从节点系统上，资源由mesos决定，不受resources标志的控制。
最近的例子：
具有16gb内存的从属设备。2个docker容器在其上运行，总共分配了6gb内存。实际使用量约为400mb。进入盒子，检查可用内存，我看到机器上有~9gb的可用内存。在marathon提供的从服务器中，我看到可用的内存不足300mb，因为我想要部署的容器需要2gb，所以应用程序部署就卡住了。重新启动从属服务器解决了问题。
我查看了确定可用内存的代码，它没有任何复杂的逻辑来解释这种行为（master/src/slave/containerizer/containerizer.cpp）。
观察到类似行为的人对我如何改进设置有什么建议吗？
