Are you really sure it is CentOS 5.2 ? I am very surprised of that, as 
any 'yum update' would have update to 5.7. And for a public web server, 
I am surprised that no update at all have been done.

Could you send to us the result of :
# cat /etc/redhat-release

For example, it is what I get from a new installed machine (CentOS 6) :
$ cat /etc/redhat-release
CentOS release 6.2 (Final)

There could be other reasons why a machine becomes irresponsive 
(sleeping states for example)...
