Hi,

I am having a few problems with my server. It is throwing up intermittant errors and running quite slow. Here is the output from top:

The intermittant error I get using Firefox is:

  Server not found

Firefox can't find the server at XXXXXXX.co.

    *   Check the address for typing errors such as
          ww.example.com instead of
          www.example.com

    *   If you are unable to load any pages, check your computer's network
          connection.

    *   If your computer or network is protected by a firewall or proxy, make sure
          that Firefox is permitted to access the Web.

And on other browsers, the page just loads for about 10 minutes but never appears. The only way to resolve it is to close the browser completely as the error appears to be saved in the cache.

Has anyone got any ideas?

Many Thanks.
