我这有台debian linux做的网关，/var/log/messsages日志如下:

也不是一直报错,我发现8和12点左右报了近一个小时错（如上）,然后就好了。
报错时系统使用正常,free查看，发现还有内存剩余(未占光)。
但就不明白是什么引起的报错，如何解决，有谁遇到过类似情况吗？
用dmesg查看，多是这种错误：
allocation failed (gfp=0x20/1)
__alloc_pages: 2-order allocation failed (gfp=0x20/1)
__alloc_pages: 2-order allocation failed (gfp=0x20/0)
