Hi all again,
I am usually having 0.xx load averages but sometimes SUDDENLY it goes =
more than 100+ load averages and then it goes down again.
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?
