Hi 您好。我使用了两个月，非常棒。不过我有个问，我的机器是群晖的716+II，CPU是四核的N3160，内存加到了8g，但是跑了debug.sh后显示如下：

显示最大使用的内存只有16M，即使重新安装最新版的镜像也是如此，所以导致我跑缓存是能是prefPC:1。请问该如何解决，烦请指点，感激不尽。

根据你的启动信息，你的宿主Linux内核为3.10.108 ，而MemAvailable似乎是Linux 3.14之后才可用，也许这个就是为0的原因（https://blog.famzah.net/2014/09/24/memavailable-metric-for-linux-kernels-before-3-14-in-procmeminfo/ ）。
下个版本我尝试使用其他方法获取可用值以兼容低内核宿主系统。

adguard果然也是0，那应该是我的系统的问题了？

不好说，可能检测方法不一样。你可以尝试把每个容器的内存限制值都调整到剩余可用内存范围之内的值试试，或者等我弄个虚拟群晖来测试下。

好的，我自己再测试一下，有新发现再和您讨教，谢谢了。

你在容器内执行一下cat /proc/meminfo 贴出来看看

根据你的启动信息，你的宿主Linux内核为3.10.108 ，而MemAvailable似乎是Linux 3.14之后才可用，也许这个就是为0的原因（https://blog.famzah.net/2014/09/24/memavailable-metric-for-linux-kernels-before-3-14-in-procmeminfo/ ）。
下个版本我尝试使用其他方法获取可用值以兼容低内核宿主系统。
