再看下free命令，问题就是为啥还有内存，结果报错呢？

你是尝试运行什么而提示 RAM 不足？opkg？

没有安装啥，就是当路由AP运行中的日志，使用过程中会突然无线繁忙，大约几十分钟后又恢复

日志上已经写了out of memory呀，已经出现wifi无线断掉的情况

因为你的剩余内存不足所以告诉你out of memory啊……告诉你的是你剩下的内存不够我干活了所以我干不了活了，而不是你一点内存都没有了……

981213

以及，系统在内存不足的时候是会开始杀掉系统进程的，可能你敲free下去的时候看到的已经是系统清理过一批进程之后的结果。漏了一件事……如果系统没有足够的连续内存空间供申请的话申请内存也是会失败并且提示Out of memory的
反正……32M还是用旧一些的OpenWrt吧别上LEDE了……

djjk

Linux 驱动程序的内存分配是在内核空间进行的，而free反馈的是用户空间的内存使用情况。
所以尽管你用free 看到还有剩余内存，但无法体现出内核空间的内存使用情况。
通过 cat /proc/meminfo 命令才能了解内核空间的内存使用细节。

不过通常驱动出现这种情况只能说明驱动程序写得不那么溜，缓冲区的回收不是很及时。
