这里只帖出来了关键的一部分日志的

macafee

怀疑用了REALTEK的垃圾网卡。

cfanbo

网卡也不至于用uptime显示的时间是类似重启服务器重新计算的时间一样的吧

lsstarboy

nmi是cpu方面的，具体我也不懂，但是可以检查一下cpu风扇，或者主板不稳定了。

在ports中有个cpu的bench软件，可以试一下。

cfanbo

多谢版主了！这么长时间给予的支持。再继续观察观察.

    REALTEK的网卡会产生莫名其妙的问题，容易使系统崩溃。

剑心通明

估计是硬件问题

cfanbo

真怪了，就是看不出来问题出现在哪个地方了

lsstarboy

硬件问题，突然就死了，根本不能操作系统反应时间，FreeBSD不可能记录下东西的。

cfanbo

应该不是硬件的问题的.执行ping命令的时候提示:
ping :sendto:No buffer space available＂
此问题不少有遇到.但无解决办法

最后重新做了系统.暂时没有发现什么问题的
