好像又被攻击了！！

dmesg 后发现有大量的下列信息“

代码:

swap_pager_getswapspace(2): failed swap_pager_getswapspace(2): failed swap_pager_getswapspace(2): failed swap_pager_getswapspace(2): failed swap_pager_getswapspace(2): failed swap_pager_getswapspace(2): failed swap_pager_getswapspace(16): failed swap_pager_getswapspace(16): failed swap_pager_getswapspace(16): failed swap_pager_getswapspace(16): failed swap_pager_getswapspace(15): failed swap_pager_getswapspace(11): failed swap_pager_getswapspace(16): failed swap_pager_getswapspace(16): failed swap_pager_getswapspace(8): failed swap_pager_getswapspace(11): failed swap_pager_getswapspace(8): failed swap_pager_getswapspace(11): failed swap_pager_getswapspace(8): failed swap_pager_getswapspace(8): failed swap_pager_getswapspace(12): failed swap_pager_getswapspace(8): failed swap_pager_getswapspace(10): failed swap_pager_getswapspace(13): failed swap_pager_getswapspace(8): failed swap_pager_getswapspace(11): failed swap_pager_getswapspace(6): failed swap_pager_getswapspace(5): failed swap_pager_getswapspace(5): failed swap_pager_getswapspace(5): failed swap_pager_getswapspace(8): failed swap_pager_getswapspace(4): failed swap_pager_getswapspace(16): failed pid 11891 (httpd), uid 80, was killed: out of swap space

发生问题时服务器运行很慢，无法远程进行连接。

停止web服务后就会变得很快，而且负载也很低。

请教大家有没有遇到过类似的情况。

机器配置：

双AMD 64+2G内存+千兆网卡。

服务是 apache+mysql+discuz

分析了几天，实在不清楚。

低调.

检查服务器的安全配置！

和配置没有关系啊！

swap_pager交换页面,交换区不足.

低雕点.
