Hi

I have a trouble with centOS 4 

The process kswapd0 eat almost all my memory space, and also this process
get almost 100 percent of cpu, and the box go slow

I have read that this problem is fix when the kernel is upgrade but I do not
know hot to update my kernel. when I type yum list \kernel*  I get the
following list:

[xxx at xxxxxx]# yum list \kernel*
