More notes on this issue....
nothing has been changed on this server as far as hardware is concerned. I had some trouble with the latest update from e-smith, and in the past 5 days the awstats module has stopped working (just noticed this last night). We load tested the server on saturday, and it did have a hard time restarting httpd, however we did get it back up and running and the server has been serving just fine since then.
Any help would be appreciated as I have got all of the PostNuke Documentation Project housed here and do not want to be offline, but then again, who ever does want to have a server down

thanks,
Steve MacGregor
