上面说是没有空闲内存，交换区有吗？

free -m

有啊,在安装时就已经设置好了,有1.4G多呢,可是我用了free -m看了一下,显示如下,惨1好像没了,要怎么弄啊
[root@localhost ~]# free -m
total used free shared buffers cached
Mem: 503 493 10 0 7 304
-/+ buffers/cache: 181 321

看,这是我的分区表,
[root@localhost ~]# fdisk -l

Disk /dev/sda: 160.0 GB, 160041885696 bytes

搞定了
激活用
swapon /dev/sda4

现在显示是
