After switching to the 2.6.32-573.22.1.el6.x86_64 kernel (CentOS 6) a few weeks ago I have noticed that my servers are now reporting a much higher idle load.

The servers are being monitored with Zabbix, and there is a clear difference between the older kernel 2.6.32-573.12.1 and the newer 2.6.32-573.12.1.

I can see the problem on both physical and virtual servers.

You can see the Load Average chart here from one of our servers:

The server is pretty much idle all the time, but the load average increased from 0.001 to 0.300 when updated to the new kernel.

Is anyone else seeing the same behavior?
