软件：
Marathon 1.1.1， Mesos 0.28.1
问题：
有时我们注意到从Mesos到Marathon的资源非常少，导致应用程序陷入“等待”状态。州。在从节点上，系统资源由Mesos确定，不受“资源”控制。旗。
最近的例子：
Slave拥有16GB内存。在其上运行2个docker容器，总共分配了6GB的mem。实际使用量约为400MB。上机并检查可用内存我看到机器上有~9GB可用。在Marathon的那个奴隶的报价中，我看到有点不到300MB，而且由于我想部署的容器需要2GB，因此应用程序部署被卡住了。重新启动从站可以解决问题。
我查看了用于确定可用内存的代码，但它没有任何可能解释此行为的复杂逻辑（master/src/slave/containerizer/containerizer.cpp）。
是否有任何观察到类似行为的人对如何改进设置有任何建议？
