Hi
I am using :
OS : CentOS release 4.3 (Final)
CPanel Version : WHM 10.8.0 cPanel 10.8.1-R113
Kernel Version : 2.6.9-34.ELsmp
I am observing excessive server load. Usually it runs at 20-30 cpu and spikes up to 65 cpu when I have to stop exim to bring it down.
I have been complaining about high server loads for the past 2 months and everytime I was told that there is nothing wrong with the version of the kernel that I have.
Now, other people using Cent Os 4.3 have reported similar issues with high server load and memory management.
Please read this thread : http://forums.cpanel.net/showthread.php?t=54280&highlight=centos+high+server+load
Read the bug report at : http://bugs.centos.org/view.php?id=1174
have thoroughlly checked my box and there is nothing "unusual" happening on my server that should cause such high server loads, almost to the tune of 70 CPU ??? All that I can see if that the server load goes high while waiting for an i/o read from HD.
My current top shows :
