Hi,
I have a CentOS 5 box, but it has a very strange problem.
I have a script that each hour, it parse the Digg and the MetaCafe Rss for example.
But after some days, it stop works, the server cannot resolve the digg or Metacafe IP.
Even WGEt doesnt work on thats sites.

Reseting Apache bring no results.
Reseting the box , makes everything all right !

The machine doesn´t have any type of firewall running(Iptables, etc..)

Any idea what´s happening ?
