Server rentals :: NFOservers.com

Okay personally I found nothing alarming but im really new to server hosting. if I give you the log could you look through it maybe.

Okay it seems whenever I don't look at the console for a while I go back and the only thing displayed is "conection reset" then to find out the server has been down for the past 5 hours. This has happend to me multiple times and I was wondering how to fix it.
