I posted about this same server a few days ago, no time to look for my post to add this to it

cpu over the top, have suspended ALL sites on the server (they are still suspended), I keep stopping apache, have cleared disk drive, mail queue, domlogs, everything I can think of and the cpu won't come down even with all the sites suspended
The cpu keeps going over 200 (with all the sites suspended!!)
Don't know what else to do :(
Here is c/p from top as of 3 minutes ago

How about ... unplug the lan cable .
what is the load ?

After a reboot do you still have a high load?

run top and hit shift+T to short by time mayb see if anything is stuck

run netstat -nap | grep 80 | more see if your being DoSsd

run ps auxwww see what all is actually running

Look at your TOP output:
343 processes: 226 sleeping, 117 running

You have 117 processes running -- by the looks (from the partial output), most are sadc -- whatever that is.

You are not out of memory, you just have 117 CPU intensive processes that all try to run at once maxing out both of your CPUs.

Anyone knows what sadc is? Worth tracking down...

EDIT: Oh, I see "System activity data collector":
http://linuxcommand.org/man_pages/sadc8.html

But why do you have so many of them running?

What OS? Control panel?

I don't know what those sadc are but they are fishy if there are 100+ processes of those~ :stickout:

Thanks everyone. I disabled sysstat but it kept coming back. I finally contacted my server providers and they are working on it, since it seemed to be something I couldn't fix from my end.
So I'm crossing my fingers.
