While it was having 97+ load averages i did 'top -n -S' but didnt show = anything that wastes so much resources.=20 I tried tcpdump if there was an incoming attack but didnt notice = anything, I also checked ipfm, tcpstat, trafshow but there wasnt any = badwidth usage. I am worried for 3 things: 1. some type of attack 2. hardware problem 3. customer's program that wastes resources Do you have ANY ideas? OR any utilities that will give me more = information?
