Hello, I'm not sure what to read out of this but my server has been in unusally high load today. It does not go below 4.0.

Same noticed here on our pre-production server that should be running at almost idle.

The new kernel has increase disk performance but has also increased the load value.

CloudLinux support confirmed that there is still a bug in the latest beta kernel that should be fixed soon.

This is getting a bit confusing now. http://cloudlinux.com/blog/clnews/cl6-kernel-with-more-load-averages-fixes.php

Which kmod-lve is stable if kmod-lve.x86_64 0:1.1-9.25 is not stable?

"We removed faulty module from our repository, and installing new kernel will bring stable module."

Are you suggesting to downgrade to 1.1-9.23 which caused heavy loads?

1.1-9.23 doesn\'t cause heavy load. It just reports load averages values higher then they should be given the load on the server.
It is just the reporting issue.

I downgraded as the blog post said and rebooted. Now ~3 hrs later my server rebooted itself. Can\'t see a reason in /var/log/messages for it.

Strange. You still have old kmod-lve. 
Try doing:
yum downgrade kmod-lve-2.6.32-379.14.1.lve1.1.9.9.el6.x86_64-1.1-9.23.el6.x86_64 --cloudlinux-updates-testing

That should downgrade dependent file as well

Ok, now it looks like this:

kmod-lve-2.6.32-379.11.1.lve1.1.9.8.2.el6.x86_64-1.1-9.20.el6.x86_64
kmod-lve-2.6.32-379.14.1.lve1.1.9.9.el6.x86_64-1.1-9.23.el6.x86_64
kmod-lve-1.1-9.23.el6.x86_64
kmod-lve-2.6.32-379.5.1.lve1.1.9.6.1.el6.x86_64-1.1-9.8.el6.x86_64

Now it is good. It should say:

kmod-lve-2.6.32-379.14.1.lve1.1.9.9.el6.x86_64-1.1-9.23.el6.x86_64 
1-9.23 in here.

Strange that old command didn't downgrade it. Will need to retest it.

I have changed command in the blog to force downgrade dependent module as well:
$ yum downgrade  install kmod-lve-1.1-9.23.el6  kmod-lve-2.6.32-379.14.1.lve1.1.9.9.el6.`uname -i`-1.1-9.23.el6 --enablerepo=cloudlinux-updates-testing


It should work for any one who experienced similar issue.
